PREVIOUSLY, ON BATTLESTAR GALACTICA:-Grace Albers and I are taking a trip down to Dinosaur National Monument in Utah and Colorado.
-We checked out some cool petroglyphs and then camped the night.
-We arrived at the quarry.
Before we begin, I am going to upload two pictures of dinosaur skeletons that may be useful throughout this post. The first is the sauropod dinosaur Camarasaurus, and the second is the stegosaur Stegosaurus. When you see the labeled bones of two other sauropods called Diplodocus and Apatosaurus, you can refer to the Camarasaurus skeleton diagram below.

The vast jumble of bones from all sorts of different animals and dinosaurs is thought to be the result of the death of various animals upstream, and then their bones being washed together! This explains why most of the bones at the quarry are disarticulated (or not fossilized next to each other like they would look like in real life), and are miscellaneous bones from such a wide assortment of creatures!
Remember before, when we mentioned most bones at the quarry are disarticulated? Well, there are some bones that are articulated, most of which are part of the vertebral columns of various animals. This looks like the tail vertebrae of something!
Most of what would be considered the "cool fossils" (like skulls and claws) have been removed from the quarry. According to Dinosaur National Monuments website, the only two skulls that remain belong to Camarasaurus: here is one of those skulls!

Next time: other things at the quarry!
