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).
Spinosaurid nostrils were set far back on the skull, at least behind the teeth of the premaxillae, instead of at the front of the snout as in most theropods. [17] Those of Baryonyx and Suchomimus were large and started between the first and fourth maxillary teeth, while Spinosaurus's nostrils were far smaller and more retracted.
Furthermore, even in comparison to the spinosaurines their skulls were long. Perhaps the most proportionally-lengthened skull belongs to Suchomimus. In its very crocodilian skull, there is little to no concavity or convexity from the front (premaxillae) to the back (parietals) of the skull, unlike in spinosaurines and most other theropods. [10]

The holotype skull of Irritator challengeri, although heavily damaged in certain places, is largely complete; missing only the tip of the snout and the front of the mandible. The preserved skull is 16.5 cm (6.5 in) tall and 10 cm (3.9 in) wide, its full length has been estimated at 60 cm (24 in), based on comparisons with Baryonyx.
Some of their supposed distinguishing features are also seen in parts of the braincase of Suchomimus, their closest relative. The results of their phylogenetic analysis (with Ceratosuchops and Riparovenator scored together) yielded similar results to those of Barker et al. (2021), with the Wessex baryonychine fossils recovered as the sister ...
Deinocheirus (/ ˌ d aɪ n oʊ ˈ k aɪ r ə s / DY-no-KY-rəs) is a genus of large ornithomimosaur that lived during the Late Cretaceous around 70 million years ago. In 1965, a pair of large arms, shoulder girdles, and a few other bones of a new dinosaur were first discovered in the Nemegt Formation of Mongolia.
Ichthyovenator ' s mid-cervical vertebrae had elongate, somewhat wider-than-tall centra that became progressively shorter towards the rear of the neck, as well as well-developed keels on their bottom surfaces, traits that were shared with the spinosaurids Baryonyx, Suchomimus, Sigilmassasaurus, [6] and Vallibonavenatrix.
