High Arctic fossils reveal ancient bear's weakness for sweets

Ellesmere Island fossil site yields bear teeth with cavities and remains of berry plants



An artist’s reconstruction shows Protarctos abstrusus in the Beaver Pond site area during the late summer. An extinct beaver, Dipoides, is shown carrying a tree branch in water. Plants include black crowberry with ripened berries, dwarf birch in foreground, sedges in water margins, and larch trees in background

Two bears living in a boreal forest in Canada's High Arctic millions of years ago munched on too many sweets and didn't brush their teeth, fossil evidence suggests.

As you might imagine, those bears ended up with cavities — something that paleontologists were very excited to see.

Oldest fossils ever found show life on Earth began before 3.5 billion years ago


Researchers at UCLA and the University of Wisconsin-Madison have confirmed that microscopic fossils discovered in a nearly 3.5 billion-year-old piece of rock in Western Australia are the oldest fossils ever found and indeed the earliest direct evidence of life on Earth.

A 508-million-year-old sea predator with a 'jackknife' head



Artistic reconstruction of Habelia optata. Habelia is thought to have been an active predator, eating small animals with hard carapaces -- such as trilobites.

Paleontologists at the University of Toronto (U of T) and the Royal Ontario Museum (ROM) in Toronto have entirely revisited a tiny yet exceptionally fierce ancient sea creature called Habelia optata that has confounded scientists since it was first discovered more than a century ago.

Meet the butterflies from 200 million years ago


Newly discovered fossils show that moths and butterflies have been on the planet for at least 200 million years.

Scientists found fossilised butterfly scales the size of a speck of dust inside ancient rock from Germany.

The find pushes back the date for the origins of the Lepidoptera, one of the most prized and studied insect groups.

New turkey-sized dinosaur from Australia preserved in an ancient log-jam


The partial skeleton of a new species of turkey-sized herbivorous dinosaur has been discovered in 113 million year old rocks in southeastern Australia. As reported in open access journal PeerJ, the fossilized tail and foot bones give new insight into the diversity of the small, bipedal herbivorous dinosaurs called ornithopods that roamed the great rift valley that once existed between Australia and Antarctica. The new dinosaur has been named Diluvicursor pickeringi, which means Pickering's Flood-Running dinosaur.

Feathered Dinosaur Shimmered Like a Rainbow, Fossil Reveals


Three years ago, a farmer in the Hebei province of China uncovered a mysterious fossil and brought it to the the Paleontological Museum of Liaoning. Now, after studying the find, scientists have announced that the fossil is of a new, duck-sized dinosaur—and when it lived it had an incredible feather display that shined like a living rainbow.

An international team of scientists studying the dinosaur, called Caihong juji, made the discovery by carefully analyzing tiny melanosomes, the part of the cells that contain pigment, in the fossil, which turned up dramatic evidence of the dinosaur’s flamboyant plumage.

Their research was published by the journal Nature Communications on Monday.
