Paleontologists have been working away in a Portuguese backyard to unearth the remains of what could be the largest dinosaur ever found in Europe, University of Lisbon researchers said. Fossilized fragments from the dinosaur were first discovered in 2017 by a property owner in the city of Pombal in central Portugal while doing construction work.

Paleontologists on Thursday heralded the discovery of a previously unknown small armored dinosaur in southern Argentina, a creature that likely walked upright on its back legs roaming a then-steamy landscape about 100 million years ago. The Cretaceous Period dinosaur, named Jakapil kaniukura, would have been well-protected with rows of bony disk-shaped armor along its neck and back and down to its tail, they said. It measured about 5 feet (1.5 meters) long and weighed only 9 to 15 pounds (4-7 kg), similar to an average house cat. Palaeontologists work on the excavation of bones and fossils that belonged to a newly discovered species of bipedal armoured dinosaur, Jakapil kaniukura, in Rio Negro, Argentina February 2, 2016.

Geologists at Lund University in Sweden have mapped 300 years of research on the prehistoric marine reptiles known as ichthyosaurs. Using a uniquely well-preserved fossil, the team has also created the scientifically most up-to-date reconstruction of an ichthyosaur currently available.

New fossil birds discovered near China’s Great Wall – one had a movable, sensitive “chin”

Approximately 80 miles from the westernmost reach of China’s Great Wall, paleontologists found relics of an even more ancient world. Over the last two decades, teams of researchers unearthed more than 100 specimens of fossil birds that lived approximately 120 million years ago, during the time of the dinosaurs. However, many of these fossils have proved difficult to identify: they’re incomplete and sometimes badly crushed. In a new paper published in the Journal of Systematics and Evolution, researchers examined six of these fossils and identified two new species. And as a fun side note, one of those new species had a movable bony appendage at the tip of its lower jaw that may have helped the bird root for food. “It was a long, painstaking process teasing out what these things were,” s...

Ground-breaking Study Confirms Time of Year When Asteroid Wiped Out Dinosaurs and 75 Percent of Life on Earth A ground-breaking study led by researchers at Florida Atlantic University and an international team of scientists conclusively confirms the time year of the catastrophic Chicxulub asteroid, responsible for the extinction of dinosaurs and 75 percent of life on Earth 66 million years ago. Springtime, the season of new beginnings, ended the 165-million-year reign of dinosaurs and changed the course of evolution on Earth. Results of the study, published in the journal Scientific Reports, greatly enhances the ability to trace the first stages of damage to life on Earth. FAU’s Robert DePalma, senior author and an adjunct professor in the Department of Geosciences, Charles E. S...
