Pterosaur Flies Safely Home After 95 Million Years

uofalberta.png

With the help of University of Alberta scientists, a newly described pterosaur has finally flown home. This spectacular fossil material was discovered in a private Lebanese limestone quarry more than a decade ago and has led to what UAlberta paleontologist Michael Caldwell calls “priceless scientific findings.”

Mammals Began Their Takeover Long Before the Death of the Dinosaurs

New research reports that, contrary to popular belief, mammals began their massive diversification 10 to 20 million years before the extinction of the dinosaurs.

Antarctic Fossils Reveal Creatures Weren't Safer in the South During Dinosaur Extinction

116239_web.jpg

A study of more than 6,000 marine fossils from the Antarctic shows that the mass extinction event that killed the dinosaurs was sudden and just as deadly to life in the polar regions.

Early Armored Dino From Texas Lacked Cousin's Club-Tail Weapon, but Had a Nose for Danger

Pawpawsaurus's hearing wasn't keen, and it lacked the infamous tail club of Ankylosaurus. But first-ever CT scans of Pawpawsaurus's skull indicate the dino's saving grace from predators may have been an acute sense of smell.

Strange Sea-Dwelling Reptile Fossil Hints at Rapid Evolution After Mass Extinction

115995_web.jpg

Two hundred and fifty million years ago, life on earth was in a tail-spin--climate change, volcanic eruptions, and rising sea levels contributed to a mass extinction that makes the death of the dinosaurs look like child's play. Marine life got hit hardest--96% of all marine species went extinct. For a long time, scientists believed that the early marine reptiles that came about after the mass extinction evolved slowly, but the recent discovery of a strange new fossil brings that view into question.

Rapid Rise of the Mesozoic Sea Dragons

In the Mesozoic, the time of the dinosaurs, from 252 to 66 million years ago, marine reptiles such as ichthyosaurs and plesiosaurs were top predators in the oceans. But their origins and early rise to dominance have been somewhat mysterious.

New Evidence Connects Dung Beetle Evolution to Dinosaurs

114744_web.jpg

Researchers have found an evolutionary connection between dinosaurs and dung beetles. An international team of scientists uncovered the first molecular evidence indicating that dung beetles evolved in association with dinosaurs. The findings place the origin of dung beetles (Scarabaeidae: Scarabaeinae) in the Lower Cretaceous period, with the first major diversification occurring in the middle of the Cretaceous. This timeline places their origins approximately 30 million years earlier than previously thought. The research explores the potential of a co-extinction with dinosaurs 66 million years ago. The study was published today in the open-access journal PLOS ONE.

Newly Discovered Titanosaurian Dinosaur From Argentina, Sarmientosaurus

Scientists have discovered Sarmientosaurus musacchioi, a new species of titanosaurian dinosaur, based on an complete skull and partial neck fossil unearthed in Patagonia, Argentina, according to a study published April 26, 2016 in the open-access journal PLOS ONE by Rubén Martínez from the Laboratorio de Paleovertebrados of the Universidad Nacional de la Patagonia San Juan Bosco (UNPSJB), Argentina, and colleagues.

Leg-Wing Cooperation in Baby Birds, Dinosaurs Is Key Transition in Origin of Flight

New research based on high-resolution x-ray movies reveals that despite having extremely underdeveloped muscles and wings, young birds acquire a mature flight stroke early in their development, initially relying heavily on their legs and wings to work in tandem to power the strenuous movement. The new study, published today in the journal PLOS ONE, is important for understanding the development of flight in modern birds and reconstructing its origins in extinct dinosaurs.

Paleontologist Finds That Ligaments in Some Dinosaurs’ Necks Helped Them Graze More Efficiently

Dino Dinner, Dead or Alive

When asked to think of meat-eating dinosaurs we usually conjure images of voracious predators chasing down helpless prey. These visions are no doubt inspired by the depiction of species such as Tyrannosaurs rex and Velociraptor in the movie Jurassic Park; however, new research conducted at Trinity College Dublin suggests that many of these species might be better remembered as oversized, scaly or feathered hyenas.

How to Survive Extinction: Live Fast, Die Young

A team of international paleontologists demonstrate that ancient mammal relatives known as therapsids were suited to the drastic climate change by having shorter life expectancies and would have had a better chance of success by breeding at younger ages than their predecessors.
