New Fast-Moving Land-Dwelling Crocodile Relative Discovered in Triassic Britain Paleontologists have discovered a new species of early crocodile relative from the Late Triassic period, approximately 215 million years ago, in Gloucester, UK. Unlike modern crocodiles, this species, named Galahadosuchus jonesi, lived entirely on land and had a lightweight, slender build that allowed it to move quickly, resembling a greyhound in form and agility. Its long legs and agile body suggest it hunted small animals such as early mammals, reptiles, and amphibians in dry, upland terrain. The fossils were recovered from fissure deposits in southern Wales and southwest England, where animals were naturally buried over time. Researchers distinguished this species from the closely related Terrestrisuchus by identifying 13 unique anatomical differences, confirming it as a new species. The discovery sheds light on ecological diversity before the Triassic-Jurassic mass extinction, helping scientists understand how prehistoric species adapted to environmental changes. The species name honors both Arthurian legend, reflecting its upright posture, and a former teacher, David Rhys Jones, who inspired the lead researcher. The findings were published in The Anatomical Record, contributing to knowledge about early crocodile evolution and terrestrial adaptations.

Compared to Richard Attenborough who was 5’7” or 1.702 meters in height. Obviously Barina is a big animal and I felt the visual difference was necessary.

Fossilized crocodylomorph tooth of a Iharkutosuchus inside of a gem jar showing feeding wear on the crown.

A fossilized crocodylomorph tooth of an Iharkutosuchus makadii from the Csehbánya Formation in Veszprém County, Hungary. Unlike the leaf-shaped teeth of herbivorous crocs like Simosuchus, this genus evolved mammal-like dentition. #FossilFriday

Old and inaccurate Sebecid illustration I did years ago! Head shape is slightly wrong and good lord those cow splotches!!! Langstonia and Sebecus were on my mind whilst scribbling this piece out.

As stated already, the "super croc" did not live with Spinosaurus (or Carcharodontosaurus), and this giant crocodylomorph was extinct and fossilized by that time. However, it did live alongside Suchomimus and Eocarcharia, as well as Ouranosaurus.

The serration-like features often present on the carinae of crocodylomorphs has occasionally made collectors mistake them for baryonychine spinosaurids. This material is often lumped into Elosuchus, but there could potentially be other large crocs.

Borealosuchus is a neat croc. The genus persists for a good while after the K-Pg mass extinction, all the way into the Eocene. You can also find B. sternbergii material right above the end Maastrichtian layers as well.

Mahajangasuchidae is interesting. Kaprosuchus and Mahajangasuchus are the only two described mahajangasuchids, but are separated by around 25+ million years. Mahajangasuchus is also the reason Kaprosuchus is no longer considered a "land croc".
