Hi, I recently got this cretaceous mammal tooth from the Hell Creek formation, and I was wondering if you may help me find the scientific name of the species that it belonged to. I've done some research and learned that it was the premolar of a Multituberculate mammal. This order of mammals was diverse and there were many species. I think it might be one of the members of the Genus, Mesodma, Yet I could be wrong. I tried to narrow it down to the exact species, yet there are few examples to help me pinpoint to a certain Id. This tiny tooth is from Garfield County, Montana. it is from the late c

There's a new fossil ungulate-related article available online if anyone is interested: Nicolás R. Chimento; Federico L. Agnolin (2020). Phylogenetic tree of Litopterna and Perissodactyla indicates a complex early history of hoofed mammals. Scientific Reports 10 (1): Article number 13280. doi:10.1038/s41598-020-70287-5. The perissodactyl affinities of litopternans have been previously suggested by DNA-based analyses, but the paper by Chimento and Agnolin is the first morphology-based cladistic analysis to support a relationship between Perissodactylia and Litopterna.

New update from the Cretaceous of Romania :)
The Amateur Paleontologist posted a topic in General Fossil Discussion
Hey everyone - hope you're all well Wanted to share this (in part cause I'm half Romanian ).. It's a conference poster presenting some recent research findings regarding a productive vertebrate microsite from the Maastrichtian (Late Cretaceous) of Hatzeg Basin (Romania). It reports some new micro-vertebrate material, including crocodile teeth, lil' bones and even eggshell. Voicu, Vasile & Csiki-Sava (2018). The Cretaceous Swamp just gets bigger: new data on the faunal composition of the Pui Swamp microvertebrate bonebed, Maastrichtian of the Haţeg Basin. The Tenth Intern- 3 replies

Hello! Interning archaeologist, and we don't have fossils on hand for a comparison collection! I came across this partial tooth in a bag of faunal material. Could anyone help me out? I'm not familiar with fossil fauna, but I know this was some sort of grazer. Width is about half an inch. Much appreciated!

Hey all, yesterday my wife (CCNHM collections manager Sarah Boessenecker) and I wrote about some of our recent finds from Folly Beach, SC. Collecting fossils there is quite easy, and if you're there for non-shark teeth, there's essentially no competition since that's all anyone ever looks for there. The fossils of Folly Beach have never been written up, and I'm getting more and more curious about them - particularly fossil marine mammals. If anyone finds marine mammal earbones out there, I'm dying to take a look! We've already gotten a nice donation from Ashby Gale, Edisto SP range

Hello there! I need your help. I've collected this two in a late Pleistocene conglomerate.

Beasts Of Eden: Walking Whales, Dawn Horses, And Other Enigmas Of Mammal Evolution
siteseer posted a topic in Fossil Literature
a book review of: Beasts of Eden: Walking Whales, Dawn Horses, and Other Enigmas of Mammal Evolution by David Rains Wallace. University of California Press. 2004. It is always great to see a new paleontology book at my local bookstore. It is especially intriguing when it concerns a group of organisms other than dinosaurs, the subject of the vast majority of them. "Beasts of Eden" is about the evolution of mammals but with a twist. The author, David Rains Wallace, chose to approach the science through art. He uses two famous murals by Rudolph Zallinger, "The Age of Reptiles" and "The Ag- 2 replies

a book review of: The Beginning of the Age of Mammals by Kenneth D. Rose. Johns Hopkins. 2006. $160 retail hardcover. Today, when we think of prehistoric mammals, images of mammoths, wooly rhinos, and Smilodon might come quickly to mind but they date back only to the recent ice ages - mere moments ago in geologic time. If your first thought was of Oligocene oreodonts, entelodonts, or hyaenodonts, then you might have a better idea of how many entire families of mammals had already diverged and died out even before the Oligocene Epoch started 34 million years ago. "The Beginning of the
