I'm finishing my undergraduate thesis, but I need to describe a species that has actually been published as Euselachii(a cohort of chondrichthys) gen. et sp. indet.. I agree this name, So in systematic paleontology whether it is correct to still use "Euselachii gen. et sp. indet." as its name? In addition, if I Find one species but consider it as other kind of Euselachii but still is gen. et sp. indet, how to name the latter? Thanks so much.

I recently did a bad thing and took a spontaneous punt on a claw without much info. I'm wondering if anyone could tell me anything at all about the look of it? Does it even look dinosaurian? Due to the size & condition, I wouldn't be shocked if it was a replica of some sort, even though I can't find anything close online. I just can't make a decent judgement call on it being fake from eyeballing these photos. The seller was obviously not the collector of the specimen (they couldn't even positively identify it as a claw) and was open about having no knowledge of the details surrounding it; all I have to go on, is that the seller was on the South coast of England and other fossils they had for sale included mostly British ammonites, Ichthy and Plesiosaur verts. They also described it as "quite heavy". The photos aren't particularly clear, as they're from the seller; I will update with better when it arrives. I've brightened/enhanced them the best I could, so there are distortions in the detail, and the colours/sheen might not be quite true to life:

Silicified specimen from Jurassic/Cretaceous/Paleogene marine sediments of Małopolska region, Poland. From secondary deposit, so precise age and locality unknown. Similar to a humerus, e.g. of a turtle. Or is just a sponge?
