2020年4月23日 · I'm trying to ID this horse tooth from Peace River, Florida. Looks like a subhypsodont. My best guess is Merychippus, but please let me know what you think.

2020年1月13日 · The other tooth, as you seem to suspect, is far more interesting. It is what in the old days would have been placed in the genus Merychippus. Today most of the species formerly placed in Merychippus have either been placed as primitive species in other genera or have been assigned to newly named genera such as Acritohippus and Scaphohippus.

2011年10月8日 · The thing to keep in mind is that species that used to be assigned to Merychippus have been reclassified under more recently-described genera. As an added note, for horse teeth (and other mammals) of any age, it is best to photograph them so we get a view straight at the biting surface) and at least one side view with a ruler in the shots so we ...

2023年5月27日 · Merychippus goorisi, Austin Co. Barstovian, Miocene Mar, 2022 It seems more recent studies have determined Cormohipparion goorisi to actually be of the genus Merychippus, a variety of three-toed horses well known from the American Miocene. At least in 1981, this species was the oldest known hippa...

2022年9月18日 · My last time out hunting was 2 weeks ago, just before the deluge. Found some nice items including 2 small upper horse teeth, and then stopped at a hunting friend's home, where he sold me a number of fossils, including 4 additional small horse upper molars. 1st tooth I believe to be Merychippus fr...

2024年3月25日 · In 1942, P. C. Henshaw identifies one of the horses from Tonopah as Merychippus calamarius. A number of researchers have lately, ie, R. H. Tedford et al 2002, considered M. calimarius and M. Intermontanus to be the same species, an opinion I agree with base on my collection of horse fossil from the Bastrow fauna and Tonopah fauna.

2021年6月24日 · Finally behind the premolars are three molars, the first molar that erupts about 1 year after birth, the second molar that erupts at about age 2, and the third molar that erupts at age 3 to 4. Older members of the horse family, such as Pliohippus and Merychippus, had four premolars instead of three.

2015年12月16日 · I found this tooth in Hogtown Creek in Gainesville, Florida yesterday! I need some help to identify it. Here in Gainesville we have the Miocene Epoch prevalent in our fresh waters.

2020年10月19日 · This tooth for sale caught my eye and was hoping someone could help ID it. It was purportedly found in Miocene deposits of Arizona and I _think_ it's a late wear stage cheek tooth of Pliohippus sp. I do not have measurements at this time. Thanks for the help!

2024年12月28日 · Happy New Year Jack! The first picture is a cervd vs a dromomerycine ( see Florida Fossil Vertebrates, pg 269, for pictures of dromomercyds ) If it is Miocene, then the tooth would be from the Late Hemphillian (no true cervids are known from earlier then the Late Hemphillian in North America ) and is Eocoileus gentryorum from the Bone Valley of Florida, ( …
