Crazyhen Posted November 8, 2021 Share Posted November 8, 2021 This piece is found along with Keichousaurus in Yunnan, China. That is, it’s Triassic. Any idea what is that? The “spines” measure about 10cm in length. 3 Link to comment Share on other sites More sharing options...

pachy-pleuro-whatnot-odon Posted November 14, 2021 Share Posted November 14, 2021 Looks like the gastralia of a intermediate size sauropterygian, likely some kind of nothosaur.
