My kids just got back from a camping trip where they found lots of Belamnite fossils. (Yes, they found them on private land.) I’ve seen these fossils on hikes, but I’ve never found out much about them. They are very common in the Cretaceous rock layers of Wyoming.
I was interested to find out more about these extinct marine creatures, but even more surprised to find out we have a state fossil. The Wyoming state fossil is called Knightia and you can see it here. According to this site, Wyoming is one of only two states to have a state dinosaur. Ours is the Triceratops, probably not much of a surprise if you live here. Many, many Triceratops skulls have been found in Wyoming, but a complete skeleton of this dinosaur has never been found anywhere. Strange, since it’s so large.
