Lapparentosaurus is a sauropod, potentially a macronarian, from the Majunga Basin, Isalo III Formation, Madagascar. It is known from partial remains from several indviduals of various sizes. It was about 15 meters long and 6 meters tall, and lived in the Bathonian age of the Middle Jurassic, anywhere between 168 and 166 million years ago. It seems as though it took 31 to 45 years to reach sexual maturity, and was relatively fast growing. Though there are quite a few remains have been found, there really isn’t a detailed description of it yet.

A new species of an extintc chimaera Edaphodon snowhillensis is described based on a complete dentition collected in the Snow Hill Island Formation of James Ross Island, Antarctica.

 Edaphodon snowhillensis represents the most complete dentition of a holocephalian fish from the Southern Hemisphere and the earliest record of the genus Edaphodon from the Antarctic and the Weddellian Biogeographic Province. Also, E. snowhillensis is the southernmost specimen of this genus and according to the size of the tooth plates is one of the largest chimaeroid fish known. 

Dinomaniacs, unite! One of our own needs our help. My cousin Justin Hall, a paleontologist known for his work on the flight of Microraptor (video here), recently had the great misfortune to lose his home and work to a fire. He lost everything in the flames, including his doctoral research and a dear friend who was helping to warn others in the building. Justin managed to save his girlfriend and his dog, but in the act suffered severe burns that required several days of hospitalization after part of the flaming kitchen ceiling collapsed on him. If you are willing, please donate at the website below. Proceeds will go to help Justin get back on his feet, from hospital bills to housing to rebuilding his research:

A Whale Inside A Whale, That Was Eaten By A Shark, Discovered In Egypt

t’s like a prehistoric turducken, but on a colossal scale: Scientists in Egypt have discovered the remains of a 40 million-year-old whale with another whale inside it, and researchers believe the two were then eaten by sharks.

The smaller whale found inside the fossils of the 60-foot-long basilosaurus may have been a fetus. However, basilosaurus had some pretty unusual dining habits. Like today’s orcas, this fierce and ancient predator was known to eat other whales, so the whale inside might not have been a fetus so much as a meal.  Read more

New species of dinosaur, the regaliceratops, discovered in Canada

When fossil experts first clapped eyes on the skull, it was clearly from a strange, horned dinosaur. When they noticed how stunted the bony horns were, its nickname, Hellboy, was assured.

The near-complete skull of the 70 million-year-old beast was spotted by chance 10 years ago, protruding from a cliff that runs along the Oldman river south of Calgary in Alberta, Canada.

Painstakingly excavated, cleaned up and measured since then, the fossilised remains have now been identified as a relative of the three-horned triceratops, and the first example of a horned dinosaur to be found in that region of North America.

Some 240 million years ago, this 8-inch-long critter lived in a large lake, in a fairly warm, subtropical climate. But it didn’t have the kind of shell modern turtles have, says Hans-Dieter Sues, a curator at the Smithsonian’s National Museum of Natural History in Washington, D.C.

“It has the real beginnings of the belly shell developing,” says Sues, “little rib-like structures beginning to fuse together into larger plates.”

First evidence that dinosaurs laid colourful blue-green eggs
It should be raptor egg blue instead of robin egg blue. Some modern birds lay colourful eggs, but now we know it's a trick their dinosaur ancestors used too.

The American robin lent its name to a striking shade of blue, but the vivid hue may have been colouring eggs long before the bird evolved – perhaps long before any birds evolved. It may have appeared in the dinosaur ancestors of birds that lived 150 million years ago.

Isn’t this little guy cute? Don’t you want one of your very own? Yes you do. I have this little guy over here. He’s cute too, but he’s only small. Now there’s a bigger one. Go get one.

Who doesn’t want their very own pet trilobite? Now you can have one too!

It’s easy to find plush models of large prehistoric animals like dinosaurs, mammoths, and saber-tooth cats. But here at the Paleontological Research Institution (PRI), we recognize that creatures both large and small are a huge part of life on Earth. Our wildly successful plushie line, Paleozoic Pals, was designed to bring lesser-known and lesser sized -yet just as important- fossil creatures to life for the community of scientists, students, and the public as a whole to enjoy.


New Fossil Discovery - “Olive” A Primitive Horse Ancestor From The Green River Formation

In the spring of 2015 the Eocene aged Green River Formation near Kemmerer, Wyoming yielded another amazing fossil discovery.  A fully articulated primitive horse ancestor, since nicknamed “Olive”, was found by brothers Mark and Mike Oliver.  While this locality is known world wide for it’s amazingly preserved fish fossils, they immediately knew they had discovered something very different and special.  Read more…


Four-legged fossil snake is a world first

The first four-legged fossil snake ever found is forcing scientists to rethink how snakes evolved from lizards.

Although it has four legs, Tetrapodophis amplectus has other features that clearly mark it as a snake, says Nick Longrich, a palaeontologist at the University of Bath, UK, and one of the authors of a paper describing the animal in Science.

Tetrapodophis was originally found in the fossil-rich Crato Formation in northeastern Brazil several decades ago. But its legs can be difficult to see at first glance, and it languished in a private collection after its discovery, assumed to be unremarkable.  Read more
