Fossil of the week: revived!

I've been slacking, I admit it. Here's the challenge of the week: The photo below is definitely a squamosal off of a chasmosaurine ceratopsian. The question is which one? Pleas guess int he comments section.

Pentanogmius now on display!

Our new specimen of Pentanogmius evolutus, RMDRC 09-015, is now on display in the marine hall. This specimen was collected from the lower Niobrara chalk in Lane Co, Kansas earlier this year. Missing only the tail, this is one of the most complete and one of the few articulated specimens ever found of this uncommon fish. It's deep body and giant sail make it over 3 feet tall, with a total length of 5-6 feet. Pentanogmius was shown in the National Geographic IMAX film Sea Monsters, along with our Dolichorhynchops and Xiphactinus specimens also on display in the marine hall. As always, our exhibits are constantly changing, so come by this holiday season and see what else we're working on.
