Reconstructing the skull of Razanandrongobe sakalavae
4 July 2017
Computed tomography of the fossil cranial bones of Razanandrongobe sakalavae (this is the name of this Jurassic crocodylomorph) provided information on the tooth replacement process and tooth/root size. The largest dentary tooth is 14 cm long and the largest premaxillary tooth measures 15 cm. CT data also allowed to 3-D print the missing counterlateral bones at FabLab Milan, and so to reconstruct the front of the skull at the Natural History Museum of Milan. Technician Andrea Passoni mounts the bone pieces.

Paleontologists document the features of a giant crocodile relative — the largest and oldest known ‘notosuchian‘, predating the other forms by 42 million years
July 4, 2017
Summary: Little is known about the origin and early evolution of the Notosuchia, hitherto unknown in the Jurassic period. New research on fossils from Madagascar begin to fill the gap in a million-year-long ghost lineage. Deep and massive jaw bones armed with enormous serrated teeth that are similar in size and shape to those of a T. rex strongly suggest that these animals fed also on hard tissue such as bone and tendon.
Little is known about the origin and early evolution of the Notosuchia, hitherto unknown in the Jurassic period. New research on fossils from Madagascar, published in the peer-reviewed journal PeerJ by Italian and French paleontologists, begin to fill the gap in a million-year-long ghost lineage.
Deep and massive jaw bones armed with enormous serrated teeth that are similar in size and shape to those of a T-rex strongly suggest that these animals fed also on hard tissue such as bone and tendon. The full name of the predatory crocodyliform (nicknamed ‘Razana’) is Razanandrongobe sakalavae, which means “giant lizard ancestor from Sakalava region.”
A combination of anatomical features clearly identify this taxon as a Jurassic notosuchian, close to the South American baurusuchids and sebecids, that were highly specialized predators of terrestrial habits, different from present-day crocodilians in having a deep skull and powerful erect limbs. “Like these and other gigantic crocs from the Cretaceous, ‘Razana’ could outcompete even theropod dinosaurs, at the top of the food chain,” says Cristiano Dal Sasso, of the Natural History Museum of Milan.
Razanandrongobe sakalavae is by far the oldest — and possibly the largest — representative of the Notosuchia, documenting one of the earliest events of exacerbated increase in body size along the evolutionary history of the group.
“Its geographic position during the period when Madagascar was separating from other landmasses is strongly suggestive of an endemic lineage. At the same time, it represents a further signal that the Notosuchia originated in southern Gondwana,” remarks co-author Simone Maganuco.
