The dinosaur of the day: Allosaurus

Some of the topics & sources from our Allosaurus discussion:

• All about Allosaurus, an iconic Jurassic theropod source
• There are multiple species, including A. fragilis and A. jimmadseni source
• Debate over the species A. europaeus source
• and whether it could be A. fragilis source
• There’s also a new species (and no more Saurophaganax): A. anax source
• Plus, we get into its Bone Wars history, the Cleveland-Lloyd Dinosaur Quarry, other former species, its hunting and scavenging habits, all the pathologies, what its habitat was like, future research, and more

Fun Fact:

The first Allosaurus fossils found (by Ferdinand Hayden, a geologist who led geologic surveys of the west for the U.S. government) were thought to be “petrified horse hoofs”.
