Ludwigia Posted June 1, 2020 Share Posted June 1, 2020 I visited my favorite shark tooth site in the Miocene Burdigalian again today and made a few nice finds along with something that has me scratching my head. I'm pretty sure it's a partial mammal tooth, but have no idea what it might be. It seems to be from quite a small ruminant anyway, judging by the chewing surface, measuring in at 7mm. wide x 6mm. high. I checked out @Harry Pristis albums, but couldn't find a match. I've posted views from first the chewing surface, then 2 sideviews, the root and the last one is the side which appears to be broken. Any ideas anyone? 1 Greetings from the Lake of Constance.

PFOOLEY Posted June 1, 2020 Share Posted June 1, 2020 Cool tooth...I saw a paper describing cheek teeth from a Miocene beaver. I didn't check the scale of those teeth but a couple looked similar. 2 "I am glad I shall never be young without wild country to be young in.

Harry Pristis Posted June 1, 2020 Share Posted June 1, 2020 I have very few examples of rodent teeth from Western Europe in my collection -- none, in fact. For what it's worth, your tooth does bear a resemblance to Pseudotheridomys (Family EOMYIDAE) from the Early Miocene of the USA. I would start my research with that family. Let us know. Good luck! 3 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

Ludwigia Posted June 2, 2020 Author Share Posted June 2, 2020 I'm starting to develop strabismus from studying hundreds of rodent teeth and since I can't find an exact match as yet, I've decided to stick with Rodentia indet. That's good enough for my purposes. Thanks again to everyone who helped out. 2 Greetings from the Lake of Constance.

fossillarry Posted June 10, 2020 Share Posted June 10, 2020 I would say that the tooth is from the posterior half of a small cervid lower p2 or p3 Link to comment Share on other sites More sharing options...

Isn't it too old to be a cervid? Jess Link to comment Share on other sites More sharing options...

I've given up on waiting for a response from fossillarry. Hi Roger, Your specimen is a challenge because it might be half of a tooth and Harry, Larry, and JP are more used to seeing Early Miocene mammal teeth from North America - not Europe. There also doesn't seem to be the same assortment of fossil ID guides for Miocene vertebrates of Europe like there are for those of North America. There was some interchange of mammals during that time (cats, palaeomerycids, and probiscideans entered North America and the horse, Anchitherium, entered Europe, for example) but your specimen likely belongs to something native to Europe. Larry checks the FF maybe twice per month. I'll email him later and let him know you're still trying to nail down an ID on this tooth. While thinking about this now, it's possible Larry has a relevant paper on it. Back around 2000 when he was looking for specimens of early ruminants of Europe, I helped him find some articles on them and other groups. One of the authors was Denis Geraads. I checked a book I have on Cenozoic mammals of Europe, "Mammoths, Sabertooths, and Hominids" (Agusti and Anton, 2002, Columbia University Press). It's an overview of mammal evolution there (not an ID guide). It says that cervids did appear in Europe by the Early Miocene. I met Larry and Harry about the same time but in different states around 1989. For a few years Larry lived about 15 minutes from me. I haven't talked to JP face-to-face but I've seen him on TV.

Ludwigia Posted July 10, 2020 Author Share Posted July 10, 2020 @siteseer Thanks for the information, Jess, and that you'll try to get Larry back on track for me. I'm sure it's half a tooth and it's also possible that it's a small cervid like Lagomeryx, since they are present within this time span in Middle Europe. Greetings from the Lake of Constance.

siteseer Posted August 2, 2020 Share Posted August 2, 2020 Hi Roger, Here are two cropped photos to show the posterior part of premolars of two different artiodactyls. The posterior is the right end of the tooth in these photos. In your first photo your tooth's posterior end is on the left side. The first photo shows a Gazella sp specimen (an antelope) from the Late Miocene of China. The second specimen shows a Dromomeryx specimen but that photo didn't come with information. It's almost certainly a Miocene specimen from North America. 1 Link to comment Share on other sites More sharing options...
