Wow, thats a fantastic find! Love the spines at the edge.
-
Patrick,
Thanks!
I also found numerous turtle carapace edge pieces through out the site. But those edge pieces were so hard to combine into articulated specimens , and were more scattered out.

Patrick,
When you collect your specimens in CA, do you have to dig them out of the matrix?
Or, are they found loose in the matrix?Dave
-
@david-hanes It depends on the locality, but generally, at least some preparation is necessary. Sometimes its just a light wash and scrub under water and sometimes an air scribe and air abrasive are needed.

Are there “open” fossil sites in the Baja Peninsula? Have you ever collected in the Baja Peninsula? -
I have never collected in the Baja. The So Cal Paleo Society had a guest speaker that did a dig in Baja trying to recover a mammoth skull slated for a local museum. They had the requisite permits but it still ended up being kind of a nightmare. After that talk, I wasn’t too interested in going south of the border.

Hi @david-hanes! It seems like there are a number of mFeM numbers associated with this one specimen. I’d like to combine all of the other photos into this one upload (mFeM 78161) since they are all from the same individual and delete the other numbers associated with it. Could you add the other photos to this mFeM number? Thanks!
-
Sean,
Yes I can.
I will consolidate all the associated specimen images into Specimen number 78161 first, then delete the duplicate Specimens. All of the associated images represent an articulated assemby of the rear section on this turtle, including the neural and nucal plates. Let me know when you see all the ‘right’ and ‘left’ side images in the…[Read more] -
Thanks so much @david-hanes! This all looks good to me.

3 years, 9 months ago3 years, 9 months agoSean,
Out of the 4 disarticulated bones from Tishomingo Creek I posted today, this disarticulated mammalia (rib) bone specimen has the greatest weight and density of them all, and therefore I would call it a fossil bone.
I agree with you that it is difficult to date and identify, but too many other collectors/paleontologists have found many…[Read more] -

I appreciate your help. I will update the specimen record with this info.
This sand bar on Tishomingo Greek collected a variety of items/fossils. It was normal to find Cretaceous mollusca (the Exogyra species) along with disarticulated more recent fossil bones, even Indian artifacts.

Hi @david-hanes, this looks like the left hypoplastron of an emydid turtle. I used Pseudemys as my reference and it looks pretty similar, but I am no expert in turtles and tortoises. I think we can pretty confidently ID it down to the Family Emydidae, though.

Hey @david-hanes, ribs are notoriously difficult to pin to a specific taxon without the context of what is found within a given unit. I fear Mammalia is about as good as we are going to get in this case. As with the other specimens, we need some confirmation that these are definitively Pleistocene and not modern bone.

Thanks @david-hanes! Yeah, I understand completely. It can be so hard to tell sometimes whether a specimen is or is not a fossil (i.e., Pleistocene vs. Holocene/modern) even in areas that have a definitive Pleistocene component to the fauna. Permineralization can occur pretty quickly in modern bone, particularly in creeks, giving the specimens a…[Read more]

Hi @david-hanes! I’m pretty sure from the photos this is a raccoon tibia.

Hey @david-hanes, do you have any references for what Pleistocene formation(s) may crop out in this area? I’ve checked a few of my references and I am only seeing Cretaceous along this creek. I’m just trying to confirm that these specimens (including the tibia and rib that you posted) are indeed Pleistocene and not just modern bones that washed…[Read more]

I identified this specimen (from other fossil “moon shells”) based on its morphology. The specimen has a characteristic apex and spire, and the aperture is characteristic of this species.And not to mention that Dr. Petuch’s books have excellent color photos and photo plates.

I believe so.
I am learning more about this phylum’s taxonomy, and sometimes have to defer to the research databases and their photos, to get the genus and species names. Please get someone there at UFL to confirm the taxonomic info.
Regardless this specimen was found in Bergeron Star Pit quarry along with the other gastropoda that I just posted. -
