Its powerful tail "could inflict serious damage on opponents, such as predatory theropods or maybe even other ankylosaurs
competing for mates or territory," according to (http://www.
2012), the only known clade of ankylosaurs
from the latest Cretaceous of Europe.
The four species span a period of about 10 million years and Arbour's research shows that three of those ankylosaurs
species lived at the same time in what is now Dinosaur Provincial Park in southern Alberta.
Leaf-shaped teeth are found in dinosaurs like stegosaurs and ankylosaurs
that eat plants.
Mallon said he is hoping to see scutes, or bony plates or scales that were on the skin of ankylosaurs
Carpenter is currently studying the relationships among the known ankylosaurs
, a suborder that includes Nodosauridae and Ankylosauridae.
Famous dinosaurs in that area included predatory tyrannosaurs, the duck-billed hadrosaurs, heavily armored ankylosaurs
, and horned dinosaurs known as ceratopsians.
The teeth of some groups have been studied in depth, such as those of the sauropods (Canudo et al, 2002b), the ankylosaurs
(Canudo et al, 2004), the theropods (Ruiz-Omenaca and Canudo, 2003; Ruiz-Omenaca et al.
Stegosaurs had bony back plates and tail spikes, and ankylosaurs
sported heavily armoured bodies and bony tail clubs.
The dorsal vertebrae of La Yesa specimen have the ventral surfaces of the prezygapophyses fused where they meet on the midline, forming a concave, continuous U-shaped surface, as occurs commonly in stegosaurs and, convergently, in ankylosaurs
(Maidment et al, 2008).
He thinks the club of one kind of ankylosaur
looked like a head to its enemies.
After conversations with Josep Montane and revision of the MNCN collections, we could claim that this latter locality probably yielded the ankylosaur
bones reported by Escaso et al.
By contrast, ankylosaur
tracks are less well known in the ichnological literature and are restricted to the Cretaceous.
