Other scientists think the extensive volcanic activity in India known as the Deccan Traps may have been responsible for, or contributed to, the extinction. However, paleontologists remained skeptical, as their reading of the fossil record suggested that
Aardonyxwas the first sauropod dinosaur to be described from Africa, and its discovery has shed light on the evolution of sauropods from their earliest ancestors. It has been suggested that Aardonyx was an intermediate form between the more primitive sauropods and the more advanced sauropods of...

If you think back to what it was like during the time of the dinosaurs (or before) the kinds of animals that survived were ones that were well adapted for the current environment. If you dropped a population of modern-day bunnies into the Jurassic period, even with their ability to reprod...

We find strong support for aquatic habits in spinosaurids, associated with a marked increase in bone density, which precedes the evolution of more conspicuous anatomical modifications, a pattern also observed in other aquatic reptiles and mammals14,15,16. Spinosaurids are revealed to be aquatic ...
and over a century later, in 2010, it was reassigned to the even more obscure genus Hypselospinus. Finally, in 2012, the paleontologist and illustrator Gregory Paul decided that this dinosaur's type fossil was distinctive enough to merit its own genus and species,Darwinsaurus evolutionis, thoug...
Analysing the evolution of clade but unknowingly including things that are not part of it, or are juveniles or that splits males and females apart etc., will always impact the results and so work starts with the correct identification of specimens. While something like 20 species (and a few...
(Ankylosauria, Nodosauridae) and Mochlodon (Ornithopoda, Rhabdodontidae) (Santonian, Hungary) were analysed to investigate their dietary ecology, using several complementary methods—orientation patch count, tooth replacement rate, macrowear, tooth wear rate, traditional microwear, and dental ...
1,2 Their traces are even found on a few isolated oceanic islands, such as Spitsbergen3 and North Island, New Zealand.4Besides Antarctica and Spitsbergen, dinosaurs have been dug up from other high latitude or inferred high palaeolatitude locations.5 For instance, they have been unearthed ...
