Curation and Prehistoric sea creatures

Well, since I didn’t see a way to look at individual users’ “life lists,” I have a question about that.

From the closed thread, “Are Fossils Acceptable?”

And this thread:

So here’s the thing: when I go to my Dynamic Life List, I see this:


There is the fossil genus Exogyra, in its phylogenetic context with other bivalves. Now imagine if I had observed several genera of Gryphaeidae, as well as other families in the Ostreoidea. They would appear in their proper places as branches on the tree. Is there a database for fossil observations that has a comparable functionality, that is, one that would let me look at my observed taxa in the form of a phylogenetic tree?

I was going to ask this question in one of the existing threads on fossils, but they are all closed. Anyway, this is my concern with being redirected someplace away from iNaturalist.
