Latest Trace fossil Stories
Dinosaur droppings fossilize, giving us "hard" evidence of some of their toilet habits. Dinosaur pee did not get preserved as such, but we can see preserved evidence of it from impressions it left when it hit a soft surface such as sand. These impressions are known as urolites, while fossilized feces are called coprolites.
Scientists at the University of California, Riverside have discovered a fossil of a newly discovered organism from the "Ediacara Biota" — a group of organisms that occurred in the Ediacaran period of geologic time.
A new study by an international team of scientists, including Dr Jan Zalasiewicz and Professor Mark Williams of the University of Leicester's Department of Geology, suggests that the fossil impact humans have made on the planet is vast and unprecedented in nature – and that there's been nothing remotely like it since the Earth formed, over four and half billion years ago.
Researchers who have discovered thin-toed tracks in fluvial sandstone in Australia said they were most likely made by two individual birds that were the size of a great egret or a small heron. These ancient birds would have lived during the Early Cretaceous period.
Paleontologists have discovered a group of more than 20 polar dinosaur tracks on the coast of Victoria, Australia, offering a rare glimpse into animal behavior during the last period of pronounced global warming, about 105 million years ago.
Ancient soil biota decreased in size by up to 46 percent during period 55 million years ago.
Paleontologists have discovered the worldâ€™s oldest dinosaur burrows in Australia.
While paleontologists may scour remote, exotic places in search of prehistoric specimens, Tufts researchers have found what they believe to be the world's oldest whole-body fossil impression of a flying insect in a wooded field behind a strip mall in North Attleboro, Mass.
The fossilized trail of an aquatic creature suggests that animals walked using legs at least 30 million years earlier than had been thought.
By Dong, Lin Xiao, Shuhai; Shen, Bing; Zhou, Chuanming Abstract: Horodyskia is one of the earliest known macroscopic life forms, with a fossil record dating from c. 1.4 Ga. Palaeopascichnus represents a key Ediacaran element with world-wide distribution.
