researchers have uncovered a series of massive dinosaur trackways dating back to the Middle Jurassic Period, approximately 166 million years ago. Dubbed a 'dinosaur highway,' the site features footprints from both herbivorous dinosaurs, likely Cetiosaurus and the fearsome carnivore Megalosaurus. The discovery was made at Dewars Farm Quarry in Oxfordshire, England, and includes over 200 footprints spread across five extensive trackways, the longest of which stretches more than 150 meters. ... a skeleton is a record of the animal once it's died. Footprints are quite different in that they are snapshots into the life of an animal .... The overlapping...

Discovered in what’s now western Romania, the Transylvanosaurus platycephalus (flatheaded reptile from Transylvania) was 2 meters (6 feet) long — a relatively small size for a dinosaur, according to a new study. Its skull bones were unearthed in 2007 in a riverbed of the Haţeg Basin. In the Cretaceous Period, this region of Romania was a tropical archipelago. Dinosaurs living there were smaller than their relatives elsewhere; paleontologists think these dinosaurs were an example of what biologists call “island rule,” where large animals isolated on islands become dwarfed or stunted in their growth over time and small animals become larger....

A newly discovered batch of well-preserved dinosaur bones, petrified trees and even freshwater clams in southeastern Utah may provide fresh clues about life in the region some 150 million years ago. The Bureau of Land Management announced the find Monday, calling the quarry near Hanksville "a major dinosaur fossil discovery." Several weeks of excavation have revealed at least four long-necked sauropods, two carnivorous dinosaurs and possibly a stegosaurus, according to the BLM. Nearby, there are also animal burrows and petrified tree trunks six feet in diameter. It doesn't contain any new species - at least not yet - but offers...
