North Pacific Rim's Desmostylus, is a goofy toothed mammal, which belongs to a group with no close living relatives. Because it is unlike any living mammal, palaentologists have had a hard time figuring out its lifestyle. The Desmostylia are weird and mystifying creatures . Basically they are only found from deposits of the Late Oligocene and the Miocene. Desmostylus is assigned to four genera that have only been found in Japan and along the west coast of Mexico and the United States, to as far north as Washington. Fossils of Desmostylus were first described in 1888 by Othniel Marsh, from marine deposits collected in Alameda County, California. The fossils were considered to represent Sirenians, and subsequent fossils found in Japan were interpreted as possibly being primitive elephants or Sirenians (sea-cows). The bizarre Desmostylians has some unique physical features, such as the teeth that show pattern of wear in their enamel that are not observed in any modern mammal, and science is not yet certain just what these short-tusked, shovel-jawed animals ate. The most compelling evidence suggests they were herbivores. Comparisons have been made between desmostylians and the hippopotamus but i just read their lifestyle may have been more like that of the sea lions. I don't know if this means they ran on the bottom of the sea like a hippopotamus or swam like a sea lions? This creature I feel has still some understanding to be uncovered.

Greetings experts and aspiring experts. I bought this desmostylus molar crown a few months back. I'm thinking that it would benefit from some good, possibly professional, prep and preservation work. If you had this tooth in your collection, in its present shown condition, what would you do to have it present and preserve better? Any input is appreciated. Many thanks. Cheers.

Greetings all. I recently purchased a tooth that was said to be from the Bakersfield area. It's not that I don't believe that it is from the Temblor formation, or nearby areas, it's just that the tooth itself seems an odd color for Bakersfield. Most teeth that I have seen from there, including those from desmostylus, are much lighter all around. Maybe it hails from elsewhere? Is the color that unusual? Bad desmo hygiene? And what type of minerals in the area might contribute to such color? Manganese oxide perhaps? It seems I remember hearing it was prevalent around Bakersfield. Many thanks in advance. Cheers.

Greetings all. It looks like I'm finally getting my hands on a decent desmostylian molar from STH. While I'd prefer to have found it in the ground myself, I can make no such claim. It was a purchase. While easier on my back, the rewards are certainly less. But I'll take it. The images of the rootless tooth look like it has never even had the matrix rinsed from it, as sand grains are in evidence falling from the tooth. Does anyone have any dos and don'ts for preserving the tooth? I have dealt with shark teeth from the same formation and usually have no problem just rinsing them with a little scrub from my roommate's toothbrush. Should such treatment be avoided or duplicated? Thanks ahead of time. Cheers.

Dear fellow forum members, some time ago I acqured two desmostylian teeth, presumably Desmostylus hersperus. Only Info I got is that they are from california. I have been wondering if the smaller one shows some kind of pathology r if it is a juvenile unerupted tooth? By the way, could the chambered structure circled in red be a sand dollar? Best Regards, J

I recently acquired some amazing specimens from my good friends collection. These pieces were part of the William Pinch (8/15/1940-4/01/2017) collection. Bill is well known in the mineral community for his incredible collection of one-of-a-kind and rare minerals from around the world. Bill also collected other natural history specimens including these two wonderful fossil teeth. These fossil teeth were available in the 80s and 90s and are now very hard to acquire. I'm very proud to own these teeth from the Pinch Collection. Happy Collecting

I thought I'd post a couple shots of my haul from this last months museum dig down in Bakersfield, California. It was a decent trip, even with the last day being cut short by rain. I found over 130 perfect makos, plus a few interesting mammal teeth. I found an upper and lower Alodesmus canine, both of which are decent sized, as well as large Desmostylus molar. Unfortunately, I destroyed what was once one of the largest makos I've ever come across. At the end of the first day I took a couple last pokes with the shovel and just blasted this 3 1/8" hastalis. Really bummed me out, but thats just the nature of hunting teeth. There is always that slight risk of destroying a truly magnificent specimen, and it finally happened to me. Joe
