Evidence of the impact of the interplay of abiotic and biotic processes on the evolution of pseudosuchians is presented by Payne et al. (2023). [13]A study on the biomechanical properties of the skull of Riojasuchus tenuisceps is published by Taborda, Von Baczko & Desojo (2023), who propose that R. tenuisceps could have had a wading habit, feeding on small-sizey prey caught from the shoreline.
Using the dimensions of three specimens known as MSNM V4047, UCPC-2, and BSP 1912 VIII 19, and assuming that the postorbital part of the skull of MSNM V4047 had a shape similar to the postorbital part of the skull of Irritator, Dal Sasso and colleagues (2005) estimated that the skull of Spinosaurus was 1.75 meters (5.7 ft) long, [14] but more ...
Neck reconstructions of Sigilmassasaurus (top) and Baryonyx. The validity of Sigilmassaurus, however, did not go unchallenged shortly after it was named.In 1996, Paul Sereno and colleagues described a Carcharodontosaurus skull (SGM-Din-1) from Morocco, as well as a neck vertebra (SGM-Din-3) which resembled that of "Spinosaurus B," which they therefore synonymized with Carcharodontosaurus.

Kuzmin et al. (2024) present the reconstruction of the Kansajsuchus extensus and note the presence of significant differences in the braincase structure of pholidosaurids and dyrosaurids, questioning the close affinity of the two groups. [55] Redescription of the anatomy of the skull of Acynodon adriaticus is published by Muscioni et al. (2024 ...
The whale's remains suggest it's a smaller relative of Basilosaurus cetoides, which lived along Alabama's coast 34-40 million years ago.
Suchomimus tenerensis skull reconstruction at the Australian Museum, Sydney. Unlike most giant theropod dinosaurs, Suchomimus had a very crocodilian -like skull, with a long, low snout and narrow jaws formed by a forward expansion of the premaxillae (frontmost snout bones) and the hind branch of the maxillae (main upper jaw bone).
Annotated skull diagram of Spinosaurus. Spinosaurid skulls—similar in many respects to those of crocodilians—were long, low and narrow. [17] As in other theropods, various fenestrae (openings) in the skull aided in reducing its weight. In spinosaurs however, the antorbital fenestrae were greatly reduced, akin to those of crocodilians. [30]
Based on skeletal material from related spinosaurids, the skull of Oxalaia would have been an estimated 1.35 metres (4.4 feet) long; [5] this is smaller than Spinosaurus 's skull, which was approximated at 1.75 m (5 ft 9 in) long by Italian palaeontologist Cristiano Dal Sasso and colleagues in 2005.
