Scleromochlus taylori

Scleromochlus taylori is small (about 20 cm long) enigmatic archosaur that lived during the late Triassic in what's now Scotland. It's ornithodiran archosaur, probably closely related to Pterosauria. Interesting fact is that what's known from this animal are not actual fossilized bones but rather their impressions preserved in a sandstone.

The filamentous integumentary structures presented in this reconstruction are speculative but not beyond realms of possibility.
