Sarcosuchus – SuperCroc
Sarcosuchus – SuperCroc
As we know, the first crocodiles appeared 228 million years ago, in the Triassic Period (Mesozoic Era). Creatures considered crocodiles, apart from the present-day animals of this superorder, traditionally include all extinct Crocodylomorpha reptiles.
One of the largest and best known reptile related to present-day crocodiles was the Sarcosuchus, living in the Early Cretaceous epoch, 112 million years ago. The Sarcosuchus belongs to the Crocodylomorpha superorder, as well as the present-day crocodiles, yet it is not their direct ancestor.
But enough of such specific discussions considering the scientific classification – let’s leave it to the enthusiasts and head straight to the point 🙂
Sarcosuchus – 12 meters of length, 8 tons of weight, 132 teeth – Ladies and Gentlemen behold, a true natural-born killer.
Sarcosuchus was not known until very recently but only from a few teeth fossils and scales which were found in the Sahara desert by a French paleontologist Albert-Félix de Lapparent in the year 1940 or 1950.
In the years 1997 and 2000, an American paleontologist Paul Sereno discovered several unknown specimens, including one that was preserved almost half-completely, even the spine. Every other gigantic crocodylomorphs is known merely by a few incomplete skull fossils, which stresses the question which one was indeed of the greatest size.
Sarcosuchus – commonly referred to as SuperCroc, while really its name literally means… an overweight crocodile.
Sarcosuchus – snout
The Sarcosuchus, or alternatively, SuperCroc, apart from its great general size, also had a massive skull and jaws. However, as a matter of fact, it was relatively narrow, contrary to the prehistoric alligator – Deinosuchus.
The skull was about 1.78 meters long (5ft 10in), 1.3 m (4ft 3in) of which were jaws, which held 132 teeth, growing back over its whole lifetime. Unsurprisingly, it was not bothered by their loss, and unlike us, it did not have to make dental appointments, brr. By the way – its teeth actually were not so sharp. It had exceptionally strong jaws instead.
Sarcosuchus – bite force stronger than T. rex?
Dr. Greg M. Erickson from the Florida State University has estimated the prehistoric crocodiles’ bite force based on the present-day animals data. His estimates claim that the Sarcosuchus bite force could reach 80 kN, which is equivalent to about 8 tons of force, while the Deinosuchus could reach 10.5 tons/cm2 (23 100 lbs)! According to his research, the saltwater crocodile has a larger bite force (1.68 tons/cm2) than the commonly favored American alligator (964 kg).
Was that the true state of affairs, or was it only the pursuit of prestige and extrapolation took one step too far? We may only leave those questions pending an unequivocal answer.
Diet and prey
Although Sarcosuchus’ immense size and great bite force, it mostly ate fish (unlike the Deinosuchus or Rhamphosuchus) as well as the famous Spinosaurus. Paleontologists claim that adult crocodiles could also hunt for tortoises as well as small dinosaurs at the watering place. On such occasions the enormous jaws were used to immobilize the victim, drag it into the water and shred to pieces – not to bite or chew.
However some biologists claim that its capability of killing larger prey are overestimated, as it could be compared to a bigger version of the present-day gavial as well as the Rhamphosuchus. Nevertheless the dispute remains unsettled.
Sarcosuchus was growing throughout its life
As well as the present-day crocodiles and snakes (see: Anaconda, Python), Sarcosuchus grew in a constant manner throughout its whole life (this was established through comparison of fossil bone sections found by paleontologists). As a result, the longest and oldest Sarcosuchus crocodiles reached 12 meters of length, being twice as long as the longest present-day crocodiles. Their weight was almost 10 times as large.
As no complete skeleton was found yet, the size of Sarcosuchus was estimated based on the size of present-day crocodiles.
Sarcosuchus – eyes
Much can be said about the everyday habits of an animal by the analysis of shape and structure of its eyes. Sarcosuchus did not move its eyes around horizontally, rather vertically. Most likely it spent most of the time submerged in the river waters, seeking potential prey.
Sarcosuchus – tail
Sarcosuchus had a powerful tail, which served as a fish caudal fin. It moved it horizontally, generating a tremendous drive force, which allowed it to reach velocities in the water sufficient to hunt for fast-moving fish. The tail power was so immense that the Sarcosuchus could ‘leap’ out of the water to catch a potential victim at the watering place.
Where did Sarcosuchus live?
Sarcosuchus inhabited the North Africa. 100 million years ago, when the North Africa was a green, tropical region covered with a dense network of rivers and streams. Relatively recently (in terms of geological periods :)) this area transformed into a Sahara desert. Sarcosuchus was one of many giant reptiles that benefited from the abundance of this continent.
