John Harold Ostrom (February 18, 1928 – July 16, 2005) was an American paleontologist who revolutionized the modern understanding of dinosaurs. [1] Ostrom's work inspired what his pupil Robert T. Bakker has termed a "dinosaur renaissance".
A 2008 study of one skeleton of the hadrosaur Hypacrosaurus concluded that this dinosaur grew even faster, reaching its full size at the age of about 15; the main evidence was the number and spacing of growth rings in its bones. The authors found this consistent with a life-cycle theory that prey species should grow faster than their predators ...
Dinosaurs are unique in showing a perforate or open acetabulum, where the full extent of the socket is a hole without infilling bone. [1] acromion The acromion is a bony ridge on the outer distal end of the scapula that functions in providing an attachment for the clavicle.
This has enabled multiple full-body reconstructions of dinosaur colouration, such as for Sinosauropteryx [83] and Psittacosaurus [84] by Jakob Vinther and colleagues, and similar techniques have also been extended to dinosaur fossils from other localities. [80] (However, some researchers have also suggested that fossilized melanosomes represent ...
The Princeton Field Guide to Dinosaurs is a reference work on dinosaurs written by the paleontologist and paleoartist Gregory S. Paul. It was first published by Princeton University Press in 2010. In the United Kingdom it was published by A & C Black under the title Dinosaurs: A Field Guide. [1] [2] An updated second edition was released in ...
The simplest definition of "paleontology" is "the study of ancient life". [5] The field seeks information about several aspects of past organisms: "their identity and origin, their environment and evolution, and what they can tell us about the Earth's organic and inorganic past".

Thyreophora ("shield bearers", often known simply as "armored dinosaurs") is a group of armored ornithischian dinosaurs that lived from the Early Jurassic until the end of the Cretaceous. Thyreophorans are characterized by the presence of body armor lined up in longitudinal rows along the body.
