This large claw is tentatively identified as from the foot of a theropod called “Spinosaurus B” from Morocco. It retains several primitive features also found in large bipedal ornithischians like Thescelosaurus and Pachycephalosaurus. Future discoveries will eventually put the question to bed.
This cast Spinosaurus foot claw measures over 3.5 inches long. This is a cast of the original fossil, research grade in quality polyresin and hand-painted. Colors may vary.
