My first ever Troodon tooth. From the Horsetheif member of the Horseshoe Canyon Formation, Troodon formosus is the only Troodontid known in the formation. I’ve thrown in a photo of a dromaeosaur tooth to show just how large the serrations on Troodon teeth were. Not going to lie I yelled out of excitement when I first found it. This tooth came from the same locality as the ankylosaur tooth I posted a few months ago, AND a multituberculate 4th premolar, but I’m not aloud to post photo’s of that one. You’ll have to take my word for it!
Gastropod (snail) shell from the Horsetheif Member of the Horseshoe Canyon Formation (Campanian). Most of the shell is missing including the apex, but the aperture (whole where the body sits) can be seen in the first image.
Two views of a lambeosaurian (hadrosaur) tooth. They are diagnostic from saurolophinae by the presence of denticles running down the sides of the teeth. Currently no saurolophinae hadrosaurs have been described from the member, though Hypacrosaurus has been described in younger members of the formation. From the Horsetheif Member of the Horseshoe Canyon Formation (Campanian). This is also from the same location as the nodosaur tooth I posted a few days ago.
Quite a common macrofossil, these are teeth from Myledaphus, a genus of fresh water ray (guitar fish). These were all collected from a single local (~5m2) from the Horsetheif member of the Horseshoe Canyon Formation (Campanian). Though they are quite common a single individual could shed thousands of teeth during a lifetime. Thus the fossil record is biased towards preserving Myle remains, making them appear far more common than they would have been in the ecosystem 71 mya.
This has got to be one of the smallest fossils in my collection and one of my favourites. It was one of those “Hey, what’s this weird black spot on the ground that doesn't look like anything... HOLY FUCKING SHIT!!!” Measuring in at a grand total of 5mm, this is a nodosaur tooth from the Horsetheif Member of the Horseshoe Canyon Formation (Campanian). Out of the large bodied dinosaurs in the formation, nodosaurs are among the rarest. Only one genus is known from the formation so I have comfortably assigned it to Edmontonia.
If you want to find the good ones forget getting on your hands and knees. If your face isn't pressed up against the dirt you’re going to have an incredibly hard time finding the good stuff.
Pine cone from the Morrin member? (could have been the base of the Tolmen Member) of the Horseshoe Canyon Formation (End Campanian).
Took me a while to figure out this one, but I was only 14 when I found it. This is a cross section of a fossilized pine cone in ironstone. Generally you would avoid ironstone while prospecting for vertebrate fossils (at least in the Red Deer River Valley). It just goes to show leave no stone unturned when in the feild.
Keeping on the ornithomimid trend, here is a metatarsal IV from the left pes. Top to bottom: anterior, posterior, left lateral, and right lateral. Quite a lot of prep went into this guy, had to do a lot of gluing. From the Dinosaur Park Formation (Campanian, Cretaceous).
Phalanx 1 of digit III (pes) from an ornithomimid from the Dinosaur Park Formation (Campanian). Top to bottom: dorsal, ventral, left lateral, and right lateral. I was lucky enough to find both haves separated by several meters on the same hill.
Two teeth collected from the same location in the Horsetheif member of the Horseshoe Canyon Formation of Alberta (Campanian). Left: a champsosaur tooth Right: a dromaeosaurid (velociraptorinae, Atrociraptor?) tooth. I was lucky enough to find both halves of this tooth within 30cm of eachother.
A highly weathered tyrannosaur tooth from the Dinosaur Park Formation (Campanian, Cretaceous), belonging to either Gorgosaurus or Daspletosaurus. I posted this same tooth in the spring with all my other tyrannosaur teeth, This was the orientation it was in right when I found it.
Not too sure on the identification here but it’s likely ornithischian. Dinosaur Park Formation, Campanian, Cretaceous.
