Auspex Posted March 12, 2018 Share Posted March 12, 2018 Safe to say that it is probably an aquatic arthropod, and possibly one with an oval body plan (judging by the 'resting place'). Do we know the age of it?

piranha Posted March 12, 2018 Share Posted March 12, 2018 Diplichnites isp. - trackways, preserved in hypo-and epirelief, 1-2 cm wide, consisting of two parallel rows of straight or slightly curved, smooth oval ridges or slightly elongated tracks, 0'5-2 mm wide, orientated transverse or oblique to the mid-line, distributed in an opposite or staggered arrangement. figure from: Mángano, M.G., & Droser, M.

Auspex Posted March 13, 2018 Share Posted March 13, 2018 2 hours ago, Fitch1979 said: would the creature be prepable you guys think? It is highly unlikely that there is anything there to prep out. The feature we see is a cast, infilled by sediment. Still, much can be deduced about the creature by studying the marks it left when making its resting place. 1 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

piranha Posted March 13, 2018 Share Posted March 13, 2018 The wide track and oval resting trace were probably produced by a large cheloniellid arthropod. figures from: Van Roy, P.
