The skull was low, with rugose rough and wrinkled nasal bones and a ridge-like crest on the lacrimal bone in front of the eye.
The front of the lower jaw was flattened, and had a downwards projecting process or "chin" at the tip.
The teeth were compressed sideways and had serrations. The neck was strong and the pectoral girdle proportionally small. Part of the family Carcharodontosauridae , Giganotosaurus is one of the most completely known members of the group, which includes other very large theropods, such as the closely related Mapusaurus and Carcharodontosaurus.
Giganotosaurus is thought to have been homeothermic a type of " warm-bloodedness " , with a metabolism between that of a mammal and a reptile, which would have enabled fast growth.
It would have been capable of closing its jaws quickly, capturing and bringing down prey by delivering powerful bites.
The "chin" may have helped in resisting stress when a bite was delivered against prey. Giganotosaurus is thought to have been the apex predator of its ecosystem , and it may have fed on juvenile sauropod dinosaurs.
Specialists from the National University of Comahue were sent to excavate the specimen after being notified of the find. In , this specimen MUCPv-Ch1 was preliminarily described by Coria and Salgado, who made it the holotype of the new genus and species Giganotosaurus carolinii parts of the skeleton were still encased in plaster at this time.
The specific name honors Carolini, the discoverer. The specimen is the main exhibition at the museum, and is placed on the sandy floor of a room devoted to the animal, along with tools used by paleontologists during the excavation.
A mounted reconstruction of the skeleton is exhibited in an adjacent room. One of the features of theropod dinosaurs that has attracted most scientific interest is the fact that the group includes the largest terrestrial predators of the Mesozoic Era.
This interest began with the discovery of one of the first known dinosaurs, Megalosaurus , named in for its large size.
More than half a century later in , Tyrannosaurus was named, and it remained the largest known theropod dinosaur for 90 years, though other large theropods were also known.
The discussion of which theropod was the largest was revived in the s by new discoveries in Africa and South America.
They conceded that comparison with Tyrannosaurus was difficult due to the disarticulated state of the cranial bones of Giganotosaurus , but noted that at 1.
They estimated the skull to have been about 1. In , the paleontologist Paul Sereno and colleagues described a new skull of the related genus Carcharodontosaurus from Morocco , a theropod described in but previously known only from fragmentary remains the original fossils were destroyed in World War II.
They estimated the skull to have been 1. They also pointed out that carcharodontosaurs appear to have had the proportionally largest skulls, but that Tyrannosaurus appears to have had longer hind limbs.
Currie cautioned that it was yet to be determined which of the two animals were larger, and that the size of an animal is less interesting to paleontologists than, for example, adaptations, relationships, and distribution.
He also found it remarkable that the two animals were found within a year of each other, and were closely related, in spite of being found on different continents.
In a interview, Coria estimated Giganotosaurus to have been Sereno countered that it would be difficult to determine a size range for a species based on few, incomplete specimens, and both paleontologists agreed that other aspects of these dinosaurs were more important than settling the "size contest".
Calvo and Coria assigned a partial left dentary bone part of the lower jaw containing some teeth MUCPv to Giganotosaurus.
It had been collected by Calvo near Los Candeleros in found in , who described it briefly in , while noting it may have belonged to a new theropod taxon.
Though the rear part of it is incomplete, they proposed that the skull of the holotype specimen would have been 1.
Delgado, and is therefore the first known fossil of the genus. Calvo further suggested that some theropod trackways and isolated tracks which he made the basis of the ichnotaxon Abelichnus astigarrae in belonged to Giganotosaurus , based on their large size.
The tracks are tridactyl three-toed and have large and coarse digits, with prominent claw impressions.
Impressions of the digits occupy most of the track-length, and one track has a thin heel. Though the tracks were found in a higher stratigraphic level than the main fossils of Giganotosaurus , they were from the same strata as the single tooth and some sauropod dinosaurs that are also known from the same strata as Giganotosaurus.
In , the physician-scientist Frank Seebacher proposed a new polynomial method of calculating body-mass estimates for dinosaurs using body-length, depth, and width , and found Giganotosaurus to have weighed 6.
This resulted in an encephalization quotient a measure of relative brain size of 1. By using multivariate regression equations , these authors also suggested an alternative weight of 6.
Henderson found that Giganotosaurus and Carcharodontosaurus would both have approached They cautioned that these measurements depended on whether the incomplete skulls of these animals had been reconstructed correctly, and that more complete specimens were needed for more accurate estimates.
They also found that Dal Sasso and colleagues' reconstruction of Spinosaurus was too large, and instead estimated it to have been They concluded that these dinosaurs had reached the upper biomechanical size limit attainable by a strictly bipedal animal.
Paul suggested that the skulls of carcharodontosaurs had been reconstructed as too long in general. In , the paleontologist Matthew T. Carrano and colleagues noted that though Giganotosaurus had received much attention due to its enormous size, and in spite of the holotype being relatively complete, it had not yet been described in detail, apart from the braincase.
They pointed out that many contacts between skull bones were not preserved, which lead to the total length of the skull being ambiguous.
They found instead that the skulls of Giganotosaurus and Carcharodontosaurus were exactly the same size as that of Tyrannosaurus. They also measured the femur of the Giganotosaurus holotype to be 1.
He estimated the Giganotosaurus holotype to have weighed 6. Tyrannosaurus was estimated to have weighed 8. He conceded that with only one good Giganotosaurus specimen known, it is possible that larger individuals will be found, as it took most of a century to find "Sue" after Tyrannosaurus was discovered.
Scott Persons and colleagues described a Tyrannosaurus specimen nicknamed "Scotty" , and estimated it to be more massive than other giant theropods, but cautioned that the femoral proportions of the carcharodontosaurids Giganotosaurus and Tyrannotitan indicated a body mass larger than other adult Tyrannosaurus.
They noted that these theropods were known by far fewer specimens than Tyrannosaurus , and that future finds may reveal specimens larger than "Scotty", as indicated by the large Giganotosaurus dentary.
Giganotosaurus is thought to have been one of the largest theropod dinosaurs, but the incompleteness of its remains have made it difficult to estimate its size reliably.
It is therefore impossible to determine with certainty whether it was larger than Tyrannosaurus , for example, which has been considered the largest theropod historically.
Different size estimates have been reached by several researchers, based on various methods, and depending on how the missing parts of the skeleton have been reconstructed.
Some writers have considered the largest size estimates for both specimens exaggerated. Though incompletely known, the skull of Giganotosaurus appears to have been low.
The maxilla had a pronounced process projection under the nostril, and a small, ellipse -shaped fenestra opening , as in Allosaurus and Tyrannosaurus.
The nasal bone was very rugose rough and wrinkled , and these rugosities continued backwards, covering the entire upper surface of this bone.
The lacrimal bone in front of the eye had a prominent, rugose crest or horn that pointed up at a backwards angle. The crest was ridge-like, and had deep grooves.
The postorbital bone behind the eye had a down and backwards directed jugal process that projected into the orbit eye opening , as seen in Tyrannosaurus , Abelisaurus , and Carnotaurus.
The supraorbital bone above the eye that contacted between the lacrimal and postorbital bones was eave -like, and similar to that of Abelisaurus.
The skull roof formed by the frontal and parietal bones was broad and formed a "shelf", which overhung the short supratemporal fenestrae at the top rear of the skull.
The jaw articulated far behind the occipital condyle where the neck is attached to the skull compared to other theropods.
The condyle was broad and low, and had pneumatic cavities. Giganotosaurus did not have a sagittal crest on the top of the skull, and the jaw muscles did not extend onto the skull roof, unlike in most other theropods due to the shelf over the supratemporal fenestrae.
These muscles would instead have been attached to the lower side surfaces of the shelf. The neck muscles that elevated the head would have attached to the prominent supraoccipital bones on the top of the skull, which functioned like the nuchal crest of tyrannosaurs.
The dentary of the lower jaw expanded in height towards the front by the mandibular symphysis , where the two halves of the lower jaw connected , where it was also flattened, and it had a downwards projection at the tip which has been referred to as a "chin".
The lower side of the dentary was concave, the outer side was convex in upper view, and a groove ran along it, which supported foramina that nourished the teeth.
The inner side of the dentary had a row of interdental plates , where each tooth had a foramen.
The Meckelian groove ran along the lower border. The curvature of the dentary shows that the mouth of Giganotosaurus would have been wide.
It is possible that each dentary had twelve alveoli tooth sockets. Most of the alveoli were about 3. The teeth of the dentary were of similar shape and size, except for the first one, which was smaller.
The teeth were compressed sideways, were oval in cross-section, and had serrations at the front and back borders, which is typical of theropods.
The neck of Giganotosaurus was strong, and the axis bone the neck vertebra that articulates with the skull was robust.
The rear neck cervical vertebrae had short, flattened centra the "bodies" of the vertebrae , with almost hemispherical articulations contacts at the front, and pleurocoels hollow depressions divided by laminae plates.
The back dorsal vertebrae had high neural arches and deep pleurocoels. The tail caudal vertebrae had neural spines that were elongated from front to back and had robust centra.
The transverse processes of the caudal vertebrae were long from front to back, and the chevrons on the front were blade-like. The pectoral girdle was proportionally shorter than that of Tyrannosaurus , with the ratio between the scapula shoulder blade and the femur being less than 0.
The blade of the scapula had parallel borders, and a strong tubercle for insertion of the triceps muscle. The coracoid was small and hook-shaped.
The ilium of the pelvis had a convex upper border, a low postacetabular blade behind the acetabulum , and a narrow brevis-shelf a projection where tail muscles attached.
The pubic foot was pronounced and shorter at the front than behind. The ischium was straight and expanded hindwards, ending in a lobe -shape.
The femur was sigmoid -shaped, and had a very robust, upwards pointing head, with a deep sulcus groove. The lesser trochanter of the femoral head was wing-like, and placed below the greater trochanter , which was short.
The fourth trochanter was large and projected backwards. The tibia of the lower leg was expanded at the upper end, its articular facet where it articulated with the femur was wide, and its shaft was compressed from front to back.
Coria and Salgado originally found Giganotosaurus to group more closely with the theropod clade Tetanurae than to more basal or "primitive" theropods such as ceratosaurs , due to shared features synapomorphies in the legs, skull, and pelvis.
Other features showed that it was outside the more derived or "advanced" clade Coelurosauria. Features shared between these genera include the lacrimal and postorbital bones forming a broad "shelf" over the orbit, and the squared front end of the lower jaw.
As more carcharodontosaurids were discovered, their interrelationships became clearer. The group was defined as all allosauroids closer to Carcharodontosaurus than Allosaurus or Sinraptor by the paleontologist Thomas R.
Holtz and colleagues in Brusatte united Giganotosaurus , Mapusaurus , and Tyrannotitan in the tribe Giganotosaurini. Carcharodontosaurus saharicus.
Carcharodontosaurus iguidensis. Coria and Salgado suggested that the convergent evolution of gigantism in theropods could have been linked to common conditions in their environments or ecosystems.
Dispersal routes between the northern and southern continents appear to have been severed by ocean barriers in the Late Cretaceous, which led to more distinct, provincial faunas, by preventing exchange.
In , the paleontologist Reese E. Barrick and the geologist William J. Showers found that the bones of Giganotosaurus and Tyrannosaurus had very similar oxygen isotope patterns, with similar heat distribution in the body.
These thermoregulatory patterns indicate that these dinosaurs had a metabolism intermediate between that of mammals and reptiles, and were therefore homeothermic with a stable core body-temperature, a type of " warm-bloodedness ".
In , the physicist Rudemar Ernesto Blanco and Mazzetta evaluated the cursorial running capability of Giganotosaurus.
They rejected the hypothesis by James Orville Farlow that the risk of injuries involved in such large animals falling while on a run, would limit the speed of large theropods.
Instead they posed that the imbalance caused by increasing velocity would be the limiting factor. They also found comparison between the running capability of Giganotosaurus and birds like the ostrich based on the strength of their leg-bones to be of limited value, since theropods, unlike birds, had heavy tails to counterbalance their weight.
In , Coria and Currie found that various features of the rear part of the skull such as the frontwards slope of the occiput and low and wide occipital condyle indicate that Giganotosaurus would have had a good capability of moving the skull sideways in relation to the front neck vertebrae.
These features may also have been related to the increased mass and length of the jaw muscles; the jaw articulation of Giganotosaurus and other carcharodontosaurids was moved hindwards to increase the length of the jaw musculature, enabling faster closure of the jaws, whereas tyrannosaurs increased the mass of the lower jaw musculature, to increase the power of their bite.
In Therrien and colleagues estimated the relative bite force of theropods estimates in absolute values like newtons were impossible and found that Giganotosaurus and related taxa had adaptations for capturing and bringing down prey by delivering powerful bites, whereas tyrannosaurs had adaptations for resisting torsional stress and crushing bones.
The bite force of Giganotosaurus was weaker than that of Tyrannosaurus , and the force decreased hindwards along the tooth row.
The lower jaws were adapted for slicing bites, and it probably captured and manipulated prey with the front part of the jaws. These authors suggested that Giganotosaurus and other allosaurs may have been generalized predators that fed on a wide spectrum of prey smaller than themselves, such as juvenile sauropods.
The ventral process or "chin" of the lower jaw may have been an adaptation for resisting tensile stress when the powerful bite was delivered with the front of the jaws against the prey.
The first known fossils of the closely related Mapusaurus were found in a bonebed consisting of several individuals at different growth stages.
In their description of the genus, Coria and Currie suggested that though this could be due to a long term or coincidental accumulation of carcasses, the presence of different growth stages of the same taxon indicated the aggregation was not coincidental.
Therefore, Coria said, large theropods may have hunted in groups, which would be advantageous when hunting gigantic sauropods. Giganotosaurus was discovered in the Candeleros Formation , which was deposited during the Early Cenomanian age of the Late Cretaceous period, approximately 98 to 97 million years ago,   although Holtz provided an earlier lower bound for its age of The formation is composed of coarse and medium-grained sandstones deposited in a fluvial environment associated with rivers and streams , and in aeolian conditions effected by wind.
Paleosols buried soil , siltstones , and claystones are present, some of which represent swamp conditions. Giganotosaurus was probably the apex predator in its ecosystem.
It shared its environment with herbivorous dinosaurs such as the titanosaurian sauropod Andesaurus , and the rebbachisaurid sauropods Limaysaurus and Nopcsaspondylus.
Other theropods include the abelisaurid Ekrixinatosaurus , the dromaeosaurid Buitreraptor , and the alvarezsaurid Alnashetri. Other reptiles include the crocodyliform Araripesuchus , sphenodontians , snakes, and the turtle Prochelidella.
