While out on the last fossiling trip of 2025 in the Horseshoe Canyon Formation, we came across this really long bone. Anything this big is usually the leg bone of a hadrosaur but it was curved way to sharply for that. From the picture it looks like it could be a rib but right under the top layer of rock, it seems to be bone extended outward from there. However this is just a guess since we can't dig to actually see if it is or not.

While on a fossiling trip in the Horseshoe Canyon Formation Back in April of 2025, We stumbled upon this really pile of weird rocks (Figure 1). It didn't match it's surroundings and had a shiny interior (Figure 2). Some of them even had a few pieces of bone on them. Initially I thought that it was a coprolite, and after doing some research, it did look similar to some coprolites. It wasn't until the next few fossiling trips that my doubts about this being a coprolite grew, as I found more of the same rocks in other places near the…

Cover Image: Albertosaurus tooth Figure 1: Large theropod tooth in many pieces (Likely Albertosaurus) What To Look For? Fossilized teeth are generally shiny and dark in colour, and may be found in one piece or in many smaller pieces (see Figure 1). They are harder to find than most other fossils and depending on which species the teeth come from, your chances of finding them can decrease. In my personal experience, tyrannosaurid teeth are pretty common compared to other types, and are fairly easy to identify. Looking for certain shapes on the tooth, like serrations, can help with the identification…
