    Same with this one @gwen-kilian! Missed these comments. I think the safest thing we can do here is put a ? after Yorktown and in the notes indicate it’s possible it had originated from an unnamed Pleistocene unit. Thanks!

    Sorry this took me so long to reply to @gwen-kilian! I guess it got lost in the shuffle with all the specimens uploaded. If you tag us @username, it makes it easier for us to find these comments. It’s hard to say for sure if it’s Nothrotheriops or Paramylodon since it’s a vertebra, which can be notoriously difficult to distinguish taxonomically…[Read more]

    Hi @gwen-kilian, is there any chance there might be Pleistocene in the area? It’s not impossible this Equus tooth came from the Yorktown but it would certainly make more sense if it was Pleistocene.

    Hey @gwen-kilian could you add Class Actinopterygii to this specimen?

    Hi @gwen-kilian, do you know anything else about the locality this came from? It seems likely the specimen was collected from the Bermont Fm if it is indeed Eremotherium and not another ground sloth. Also, can you add Order Pilosa to the classification? Thanks!

    Beautiful Castoroides tooth @gwen-kilian! I was trying to figure out if there are any named Pleistocene units around Alton and that doesn’t seem to be the case. Does that line up with you research/experience?

    Hi @gwen-kilian ! Thanks for sharing your finds. The Cooper Formation is too old to have Megalodon teeth, so I think you can confidently say this tooth came from the Hawthorn Formation. Once you update that, I’ll mark the specimen as research grade!
