Nope it's not another "Is it real post."
We see many slabs posted inquiring if one of the guys is real or "fake." That auction site is full of offers of Keich plates.
Has anyone ever seen another species preserved on one of these plates? I haven't. What did they eat? From their teeth I assume fish, but where are they? Perhaps they ate soft bodied inverts that did not preserve. However, one would think with that fine-grained matrix something would show up.
Has anyone seen anything else preserved on one of these plates?
