The first fossil mammal in my collection: a partial jaw of Merycoidodon sp.
gond posted a topic in Member Collections
Hello everyone, even though I haven't reached 35 fossils in my collection like I hoped for this year, I still managed to close 2023 with my 34th fossil! The one I'm going to show you today is, in fact, this 34th fossil, which is also the first mammal fossil I've ever owned Species: Merycoidodon sp. (Leidy, 1848) Size: ~3.0 cm long Age: 34-23 mya (Oligocene, stage indet.) Origin: South Dakota's Badlands (USA) About this fossil: a partial lower jaw of this genus, with four nicely preserved teeth. I personally like how, in this specimen, the matrix is still present, which helps to keep the two parts together and just makes the fossil look nicer- 1 reply

The fossil in the images below is being sold as that of a Merycoidodon, but it looks rather small for such an animal, so I wondered if it could be from a smaller Merycoidodontid or perhaps another small ungulate like Leptomeryx. Thanks in advance for any guidance Othniel

I was told by one of my professors that this is a skull from a Miocene cave bear from Nebraska, but it looks exactly like a Merycoidodon skull to me.

I was recently given a mandible by a retiring paleontologist that I've been prepping. It was buried deeply in matrix. He had recorded it in his records as merycoidodon sp. not knowing what species of merycoidodon it is. Does anyone know if we can tell based on size alone? Here are some pics.

Oreodont Merycoidodon Teeth
JulianoLPD posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi there, guys. So, I got these from an internet auction. It's the first time I put my hands on this kind of piece. It doesn't "feel" fake or nothing, but I just want to be sure, so I thought I'd better get an expert opinion. What do you think? It's supposed to be Merycoidodon culbertsoni, from the Oligocene of South Dakota Badlands.- 5 replies

Merycoidodon ("ruminating teeth") is an extinct genus of herbivorous artiodactyl of the family Merycoidodontidae, more popularly known by the name Oreodon ("hillock teeth"). It was endemic to North America during the Late Eocene to Early Miocene (46—16 mya) existing for approximately 30 million years. Merycoidodon would have somewhat resembled a pig in appearance, but had a longer body, at about 1.4 metres (4.6 ft), and short limbs. The fore limbs had five toes (although the first one was vestigial), while the hind limbs had four. Given the shape of the limbs, it is unlikely that the animals would have been able to run fast. Unlike modern ruminants, they had a full set of teeth, although the molars were adapted for grinding up tough vegetation. Notably, they had strong, and very striking, canines. The skulls of Merycoidodon have a pit in front of the eyes. Similar pits are found in the skulls of modern deer, where they contain a scent gland used for marking territory. Although Merycoidodon was not directly related to deer, it seems likely that it possessed a similar gland, which may imply that it, too, was territorial. Oreodonts lived in large herds and moved about from place to place. They seem to have had a predilection for well-watered regions, where food was plentiful and succulent. The number of fossils found implies that, at one time, oreodonts were as plentiful in South Dakota as zebras are today on the serengeti plains.

Oreodont and Camel: Real or Fabricated?
RaideReX posted a topic in Is It Real? How to Recognize Fossil Fabrications
Good day everyone, I'm looking into these two partial mammal skulls: An oreodont Merycoidodon and a Camel Poebrotherium. I'd like some help to find out if these are all real or have been partially fabricated, enhanced, composited, total fakes.

So I bought a partial oreodont skull (Merycoidodon culbertsoni) from an auction site and i'm using it to break in my new air compressor. Here are some before and after pics. I had expected the skull to be fragile and the teeth to be pretty solid, considering how robust teeth are, but I found the opposite to be true. I've had to repair a few of the teeth as I went. They have a tendency to break apart. Luckily nothing too serious. The skull itself seems indestructible by comparison. Overall i'm very happy with how she's turning out so far.

I took a trip to Nebraska to collect the White River Formations for the very first time this past summer. I had two goals: recover a Stylemys and an Oreodont skull. I found both! I reported on the prep of the Stylemys in an earlier post on the prep sub-forum. When I saw the Oreodont, I yelled "Bingo, Oreodont!". So that's the name I gave the animal. This post will summarize the discovery, preparation, and reconstruction of the specimen. The skull was not complete, and only about 25-30% of the animal was present, so with apologies to the "Palaeo Police" , I decided that this specimen would have a greater contribution as a display piece than sitting in a drawer with other oreodont remains (which are common and numerous). Also, if any of these bones were later found to be of scientific importance, the procedures used in this reconstruction are reversible THE DISCOVERY Bingo was spotted on the side of a relatively steep butte. The first thing I saw was the partial skull. Here it is: After exclaiming (proclaiming) "Bingo!", I left the skull and immediately went to the base of the butte and started probing and digging in the two washouts that originated in the vicinity of the skull. These re-worked deposits were yielding lots of bone elements from the posterior to the anterior of the skeleton. I even managed to recover the brain cast and pieces of the skull that had washed down. Once the re-worked deposits had been thoroughly searched, I climbed up to the skull and began excavating. The top of the snout was crushed (predation?). The brain case area was also fragmented as well as the rear of the jaw. Some of this was pieced together later from elements found in the spoil at the base of the butte. I removed the skull via a "soft jacket". Here is what was recovered:

Hello Everybody, I am wondering if someone can confirm which bone this is. It is from an Oreodont "bowl of spaghetti". It has articular surfaces on three sides (both lateral faces and the end / top). My guess is that it is a proximal end of a metapodial. Is that right? If so, can anyone provide more info (metatarsal or metacarpal, digit number (assuming II or III))? I have limited disarticulated mammalian foot bones for comparison. I have dog and cat, but I still am not sure based on the comparisons. Thanks for any help.
