@1G0ld3n For Allosaurus: https://t.co/a23yzYSm3p Allosaurus jimmadseni is in lower Morrison and Allosaurus fragilis is in upper Morrison, with Saurophaganax is the very highest Morrison of eastern Colorado and Oklahoma.
All the Cleveland Lloyd Quarry mounts have a composite skull of A.j.
@HunterStack7 By age do you mean different levels in the Morrison Formation as A. jimmadseni is 5 mya older than A. fragilis. By age as individual? I'll steer you to the paper here https://t.co/1L8y9S8qll
