Ankylosaurus [nb 1] is a genus of armored dinosaur. Its fossils have been found in geological formations dating to the very end of the Cretaceous Period, about 68–66 million years ago, in western North America, making it among the last of the non-avian dinosaurs. It was named by Barnum Brown in 1908; it is monotypic, containing only A ...
Ankylosauridae (/ ˌ æ ŋ k ɪ l oʊ ˈ s ɔː r ɪ d iː /) is a family of armored dinosaurs within Ankylosauria, and is the sister group to Nodosauridae.The oldest known ankylosaurids date to around 122 million years ago and went extinct 66 million years ago during the Cretaceous–Paleogene extinction event.

In dry weight, the omer weighed between 1.560 kg to 1.770 kg, being the quantity of flour required to separate therefrom the dough offering. [32] In the Torah, it is the Priestly Code which refers to the omer , rather than to the se'ah or kab ; [ 1 ] textual scholars view the Priestly Code as one of the later sources of the Torah, dating from a ...
Talarurus was a medium sized ankylosaur, Thomas Holtz and Gregory S. Paul estimated its length at 5–6 m (16–20 ft), Paul gave a weight of 2 t (2,000 kg), [9] however, Holtz estimated it around 454 to 907 kg (1,001 to 2,000 lb). [10]
This compares to the much larger North American Euoplocephalus, 6–7 m (20–23 ft) in body length, which had teeth averaging only 7.5 mm (0.30 in) across. [7] A fragment from the left dentary (lower jaw bone) preserving these teeth was recovered, which has a curved tooth row like other ankylosaurs'.
Ankylosaurinae is a subfamily of ankylosaurid dinosaurs, existing from the Early Cretaceous about 105 million years ago until the end of the Late Cretaceous, about 66 mya. Many genera are included in the clade , such as Ankylosaurus , Pinacosaurus , Euoplocephalus , and Saichania .
Gargoyleosaurus was a relatively small ankylosaur, reaching 3–3.5 m (9.8–11.5 ft) in length and 300–754 kg (661–1,662 lb) in body mass. [3] [4] [5] Much of the skull and skeleton has been recovered, and the taxon displays cranial sculpturing, including pronounced deltoid quadratojugal and squamosal bosses.
They may have split up during the Aalenian period, more than 170 million years ago, but they were definitely in Africa by the Bathonian due to the presence of Spicomellus in Morocco. [17] There are no well-preserved remains of ankylosaurs of that age.
