An article published in the “Journal of Paleontology” describes a research on the theropod dinosaurs whose fossils date back to the Late Cretaceous and were found at the site of Ellisdale, in New Jersey, USA. Chase Brownstein of the Stamford Museum and Nature Center studied fossils belonging to various families: adrosauroids (Hadrosauroidea), tyrannosaurids (Tyrannosauridae), dromaeosaurids (Dromaeosauridae) and ornithomimosaurs (Ornithomimosauria). The Ellisdale site is sometimes overlooked but these findings can provide information on the diversification of theropods throughout North America.
