Exhibits The Science Museum of Minnesota in Minneapolis @SMMPaleo @sciencemuseummn has a number of neat skeletons on display. Each of these in the video has at least some original bone. #Camptosaurus is a classic Late #Jurassic (150 mya) #ornithopod #dinosaur that may very well be one of the ancestors of the #iguanodons. At 20’ long and around 1,000 lbs, it relied on speed to escape. Alas, #Allosaurus was speedy and armed with massive hand claws, sharp toe claws, and a mouth full of sharp teeth.
