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).
The next year, Sereno et al. described the specimen as the new baryonychine Suchomimus tenerensis. [10] The species was also the subject of synonymy disputes over Cristatusaurus and Baryonyx throughout the 1990s and 2000s. [11] [12] From 2013 to 2020, several spinosaurid fragments were discovered from the Wessex Formation in Britain.
Suchomimus is the only spinosaur known to have preserved a furcula (wishbone), which shows that spinosaurs had a V-shaped furcula. [39] Spinosaurid hands had three fingers, typical of tetanurans , and wielded an enlarged ungual on the first finger (or "thumb"), which formed the bony core of a keratin claw.
English: Figure B. Baryonychine rostrum in lateral view. A‒B, Suchomimus tenerensis (MNN GAD501); A, close up on the premaxillary crest (left side); and B, snout (right reversed, photo courtesy shared by Juan Canale); C‒D, Cristatusaurus lapparenti (C, MNHN GDF566; D, MNHN GDF565, modified from Taquet [14]); E, Baryonyx walkeri (NHM R.9951).
Given that it was named first, Cristatusaurus lapparenti has priority over Suchomimus tenerensis in the case that they become synonymized. [18] In a 2017 study, Marcos Sales and Cesar Schultz compared the holotype of Cristatusaurus (MNHN GDF 366) to the referred snout of Suchomimus (MNN GDF501). Both of them exhibit a narrow rim across the top ...
The Elrhaz Formation is a geological formation in Niger, West Africa.. Its strata date back to the Early Cretaceous, about 125 to 112 million years ago.Dinosaur remains are among the fossils that have been recovered from the formation, alongside those of multiple species of crocodyliformes.

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.
