A dinosaur claw of an indeterminate spinosaurid, likely Suchomimus tenerensis from the Elrhaz Formation in Gadoufaoua, Niger. Baryonychine spinosaurids like Suchomimus and Baryonyx are known for their robust hand claws in contrast to the more narrow morphology seen in derived spinosaurines like Spinosaurus.

Portrait of the spinosaurid Riparovenator milnerae from the Early Cretaceous of England. The remains of this theropod were found on the Isle of Wight and were initially attributed to Baryonyx. These include fragments of the skull and a series of tail vertebrae. In 2021, they were assigned to a new genus based on a combination of features of the skull bones. Like other dinosaurs from the Baryonychinae subfamily, it had a long and narrow snout, although not as specialized as that of Spinosaurus. A related Ceratosuchops from the Isle of Wight was described in the same publication. If these dinosaurs lived at the same time, they may have hunted at different times of the day or preferred different hunting grounds, but it is also possible that they were not contemporaries.

In this work, I tried to paint with color on a black base. It was a pretty unusual experience. :)

Portrait sketch of the spinosaurid Suchomimus tenerensis from the Early Cretaceous of Niger. This is one of the spinosaurids known from relatively complete remains, including parts of the skull. The length of the Suchomimus is estimated at 9.5-11 meters, but the ontogenetic stage of the holotype is unknown, so the maximum size of this dinosaur is unclear. The skull is long and very narrow, with a characteristic notch in the upper jaw. There was a low ridge along the back. Judging by the structure of the leg bones, Suchomimus preferred to hunt in shallow water. Some paleontologists consider it to be one of the species of related Baryonyx, synonymy with contemporary, but much more fragmentary, Cristatusaurus lapparenti has also been suggested. Suchomimus co-existed with unusual dinosaurs such as Ouranosaurus and Nigersaurus, as well as various crocodylomorphs.

The sketches in sketchbook with toned paper. :) It's baryonychine (speculative reconstruction with "lips") and Spinosaurus, both done without references. In the process, I used a white pencil (I have hardly used it so far) for the light parts, it turned out to be a very good volume.

A dinosaur tooth of an indeterminate spinosaurid, likely Suchomimus tenerensis from the Elrhaz Formation in Gadoufaoua, Niger. While it is likely Suchomimus, it lacks fluting typically seen in baryonychine teeth. Depending on the phylogenetic position of the dubious Cristatusaurus lapparenti, it may also potentially belong to this lesser known species. It is also possible it belongs to an undescribed spinosaurine.

A partial dinosaur tooth of an indeterminate baryonychine spinosaurid, likely a Ceratosuchops inferodios or Riparovenator milnerae from the Wessex Formation in the Isle of Wight, England. The tooth lacks fluting typically seen in baryonychine teeth, though some positional tooth morphologies that lack fluting have been described from Baryonyx.

A dinosaur tooth of a Suchomimus tenerensis from the Elrhaz Formation in Gadoufaoua, Niger. Compared to most spinosaurids which are notoriously fragmentary, Suchomimus is known from relatively complete material. The teeth of baryonychines like Suchomimus still retain very fine serrations often lost in the more derived spinosaurines like Spinosaurus. The contemporary spinosaurid, Cristatusaurus lapparenti may or may not be synonymous with this species.
