#kaatedocus

First is the Hell Creek freshwater mosasaur second is Kaatedocus, taking into account the recently described melanosomes and their potential for coloration.

Let the artfight posting begin!!!! First up, a little revenge chain with spidernoob64 - some lovely paleo friends, I'm quite proud of how these came out, too! :)

A dinosaur tooth of an indeterminate diplodocid sauropod, likely Diplodocus hallorum from the Salt Wash Member, Morrison Formation in Big Horn County, Wyoming, United States. The original species Diplodocus longus, now a nomen dubium, is synonymous with Diplodocus hallorum. While it is almost certainly from the common Diplodocus sp. due to the sheer abundance of this genus, there are many other rarer diplodocids found in this deposit such as Barosaurus lentus, Galeamopus sp., Supersaurus vivianae, Kaatedocus siberi, and Ardetosaurus viator. Diplodocid sauropods are known for their peg or pencil-like teeth, and are likely not diagnostic down to the genus or species level in the vast majority of cases. Apatosaurine diplodocid genera like Apatosaurus sp., Brontosaurus sp., and possibly Amphicoelias altus can be ruled out due to the lack of facets which are present in apatosaurines like Apatosaurus, but absent in diplodocines like Diplodocus.

2. - Kaatedocus - time period: Late Jurassic, family: Diplodocidae, fun fact: Most of it's fossil had to be thrown away, because it got damaged before examination - only 10% left

A group of Kaatedocus is mired in a mud pit, in what is now Howe Quarry. Um grupo de Kaatedocus está preso em um poço de lama, no que é hoje Howe Quarry, um sítio paleontológico.
