The scientific tourist #185 — hadrosaurs in trouble

This week’s image comes to you from the Houston Natural History Museum — it’s a mother / child pair of hadrosaurs being harried by a T. Rex:

Hadrosaurs and T. Rex

From the placard:

Hadrosaurs, or duck-billed dinosaurs, such as Edmontosaurus were among the most abundant of Late Cretaceous dinosaurs. Edmontosaurus fossils have been found in sedimentary formations of the Western Interior of North America including Alberta, Saskatchewan, North and South Dakota, Wyoming, Colorado, and Montana. These animals probably lived in herds on the eastern flanks of the Cordilleran Mountains, an ancient mountain range located approximately where the Rockies are today, and west of the Late Cretaceous Interior Seaway which extended from the Arctic to the Gulf of Mexico. Duck-billed dinosaurs were peaceable herbivores whose natural enemies probably included the giant predator Tyrannosaurus rex. This juvenile Edmontosaurus annectens specimen is about half grown.
