In Depth Sonorasaurus may look like an atypical brachiosaurid dinosaur (as in similar to the famous Brachiosaurus), but the genus actually represents the first known example of a brachiosaurid dinosaur in North America during the Cretaceous, specifically around the early/late Cretaceous boundary. This is yet further evidence that counters the now outdated theory that the … Read more
In Depth Originally described as belonging to a species of Megalosaurus in 1884, Friedrich von Huene renamed the fossils of teeth and vertebrae to Altispinax in 1923. This name reflects the size of the neural spines of the vertebrae, fossils that were later attributed to the genus after it was established upon the description of … Read more
In Depth Taurovenator is a genus of carcharodontosaurid theropod dinosaur that lived in South America during the Late Cretaceous. At the time of writing, Taurovenator is only known from partial skull remains.

In Depth It is quite surprising when you think about how Aublysodon is represented in so many dinosaur books and internet sources even though back when it was described in 1868 it was only from teeth. Still this was a sign of the times back then with other discoveries such as Troodon, which was also … Read more
In Depth Astrodon has been a troublesome genus of sauropod dinosaur, partly because of the lack of complete remains for the genus which was initially primarily named from the teeth. Astrodon also has an uncertain relationship with the genus Pleurocoelus, with some authors considering the two to be synonymous, to just some species of Pleurocoelus … Read more
In Depth Talos is so far only known from a partial post cranial skeleton that is mostly represented by the rear limbs. However when these remains are scaled to the same proportions as other more complete troodontid genera, a rough estimate of around two meters in length can be attained for the animal. Like other … Read more
In Depth Although discovered in 1972, Gallimimus was a relatively little known dinosaur until its appearance in the 1993 movie blockbuster Jurassic Park. In one of the more famous scenes of this film a whole herd of Gallimimus gets chased by the Tyrannosaurus before one slips and is killed by this predator. Although science fiction, … Read more
In Depth Currently considered to be a megalosauroid theropod, Piatnitzkysaurus was a smaller medium sized theropod of the Jurassic. As a predator Piatnitzkysaurus probably hunted other small dinosaurs and possibly even those slightly larger than itself. It is also almost a certainty that Piatnitzkysaurus would scavenge the carcasses of dead dinosaurs when able, since scavenging … Read more
In Depth The holotype remains of Murusraptor were first recovered across 2001 and 2002, but were not described in a scientific paper until 2016. Murusraptor is identified as a megaraptoran theropod dinosaur, and one of potentially large size. The holotype individual of Murusraptor has been estimated to have been just short of six and a … Read more
In Depth Lajasvenator is a genus of carcharodontosaurid dinosaur that lived in South America during the Early cretaceous. Carcharodontosaurid dinosaurs have a reputation for being some of the largest predatory dinosaurs, but Lajasvenator is at the opposite end of the scale, and represents perhaps one of the smallest carcharodontsaurid known.
