A robotic ankylosaurus tail shows that the tail club could break wood and bone with ease. This dinosaur's armour and club was used only on more threatening predators than Velociraptor. In the U.S version, it was known as Ankylosaurus, although Ankylosaurus itself lived in North America. The ankylosaurus in this fact have been Pinacosaurus.

Tarchia was a medium-sized ankylosaur, measuring around 5.5–6 metres (18–20 ft) long and weighing up to 2.5–3 metric tons (2.8–3.3 short tons). [9] [10] If ZPAL MgD I/113 indeed belongs to the genus, it would have belonged to an individual measuring 5.8–6.7 metres (19–22 ft) long.

Some dinosaurs patrol the grey wasteland of the Pacific Northwest. An Ankylosaurus, a Triceratops, and a T. rex fight and all are killed. In Mexico, an Alamosaurus egg, sheltered underground, hatches. However, crippled by inbreeding and disease, the tiny population of dinosaurs disappears.
As of 2017, there is only one find of a possible Tyrannosaurus rex footprint, dating from 2007 and described a year later. [34] A trackway made by mid-sized theropod, possibly a small tyrannosaurid individual, was discovered in South Dakota in 1997, and in 2014 these footprints were named Wakinyantanka styxi .
