I received a couple of trilobites, which the seller has given me the description, as unknown. (He has me fried).
See if anyone can help.
In photo 1 .... With 2 centimeters long, (it comes from the Cambrian Tenprano (quiongzhusi formation, Yunnan - China) Could it be a kind of Maotunia?
The other, Ordovicio ... 1 centimeter long. (Baoshan - Yunnan, Shihtian formation, China).
Encrinoides enshiensis? I saw it in a thread on this forum, and it looks like it, but it was from the Silurian.
Any clues on that stain?
