Hypacrosaurus is a Lambeosaurine hadrosaur from late Cretaceous Alberta, Canada and Montana, USA. It was about 32.8 ft (10m) long and weighed about as much as a rhino. Known from eggs and nests, juveniles through adults, and whole herds. On March 2020, paleontologists have found DNA and protein well preserved in the 75 million year old Hypacrosaurus skull.

Description

The type remains of Hypacrosaurus remains were collected in 1910 by Barnum Brown for the American Museum of Natural History.
