I will find you in every life (threat)

I am forever fascinated by the arms race between coelurosaurs and ceratopsians. Among the most famous rivals in palaeomedia growing up was Velociraptor and Protoceratops, Tyrannosaurus and Triceratops, and of course I had to add two of my faves, Gorgosaurus and Styracosaurus!

Long time followers may recognise the bottom two skulls as art I have made previously, fun fact I have been sitting on this idea for a little over two years!

Galahadosuchus jonesi was a small early crocodylomorph that lived during the late Triassic of what is now southwest England, around 215 million years ago.

About 60cm long (~2'), it had a fully upright quadrupedal posture, slender digitigrade limbs, a long tail, and a paired row of interlocking osteoderms running along its back.

Its habitat at the time was part of an archipelago of small tropical islands, in a forested karst environment full of sinkholes and caves. It would have been a fast and agile runner, and like its close relative Terrestrisuchus it was probably a generalist pursuit predator feeding on prey such as invertebrates and smaller reptiles.
