McCrea, Lockley, and Meyer observed that by this point in the history of ankylosaur research, ankylosaurs track fossils had been reported from North America, South America, Asia, and Europe. Most of these trackways were preserved in moist floodplain habitats where plant life was abundant. [7]
One notable example was Arthropleura, the biggest bug ever known at up to 10-1/2 feet (3.2 meters) long, inhabiting what is now North America and Europe. While its fossils have been known since ...
