So as you probably know (at least if you've been following us here for Stegosaurus Week), the whole point of the special week was to celebrate Stegosaurus Day at the Morrison Natural History Museum in Morrison, Colorado! But what Stegosaurus-related exhibits does the Morrison Natural History Museum even have? Well. I am so glad you asked. Let's dive on in!paleontologist Othniel Charles Marsh first named and described the genus Stegosaurus in 1877, during the famous (or rather, infamous) Bone Wars. Below, we have a picture with the four different groups of bones highlighted in red.
paleoartist Fabio Pastori of what this animal would have looked like. Meet Stegosaurus armatus, one of four species of Stegosaurus that are currently considered to be valid!
baby Stegosaurus model! This little guy below is about a foot long, and is a life-size representation of the animal that would have made that footprint. Besides being the very first baby Stegosaurus footprint discovered anywhere in the world, this footprint is especially interesting because it shows that the baby Stegosaurus was walking on its back legs, without its front legs touching the ground!
Jurassic-aged rock contains what is largely considered to be the best adult Stegosaurus hind foot track in the world!
Next, we have a VERY interesting block of fossil-containing rock!
It all started when the block was brought into the museum because of the dinosaur bones, like the rib bone you can see below from an unidentified dinosaur....
house cats) is even harder to identify, and could belong to a wide variety of dinosaurs.
The other tracks on the slab are by and large considered to be much more interesting. What you are looking at below are some more baby Stegosaurus footprints! Remember the baby Stegosaurus footprint that we discussed below, and remember the model of the animal that was thought to have made it? The model is about the size of the animal that is thought to have made the little tracks on the left in the picture below! What's particularly interesting about these footprints, however, is that they show the footprints of at least two individual Stegosaurus, each probably just a few months old, superimposed on each other! This seems like pretty good evidence that these guys were also moving in groups, just like the other slab of Stegosaurus footprints shows us with older individuals! The smaller footprint on the right (again, around the size of a domestic cat's footprint) is from a much smaller individual, probably just a hatchling! It is also possible that this hatchling was moving with the other juveniles, as well!
Stegosaurus and it's relatives? Well, check out the Homebase for Stegosaurus Week HERE to partake in more of the festivities!
