Act like Megalochelys atlas and smile, because it’s Fossil Friday! One of the largest known land turtles, scientists think this massive reptile could reach heights of 5.9 ft (1.8 m)—tall enough to look a grown human in the eye. This specimen’s shell measures some 7.4 ft (2.3 m) long and in life, it may have weighed more than 2,000 lbs (907 kg). Megalochelys lived during the Late Pliocene about 2 million years ago. The fossil on display in the Museum’s Hall of Vertebrate Origins was found in 1922 in Chandigarh, India.

Ancient Shell-Less Turtle Species Identified From 228-Million-Year-Old Triassic Era Fossil

Eorhynchochelys

(2018)

Scientists have discovered remains of a rare kind of turtle, one that lived over 228 million years ago in the Triassic era and had no shell – the most common feature of present-day turtles. The nearly complete skeleton of the ancient turtle was found by researchers from China's Institute of Vertebrate Paleontology and Paleoanthropology in the Asian country’s Guizhou province. The animal had a toothless beak and Frisbee-shaped body just like present-day turtles, but there were no signs of growing bones that form the shell. Modern turtles use the feature to enclose their vital organs, including the head in some cases, and protect themselves "This creature was over six feet long, it had a strange disc-like body and a long tail, and the anterior part of its jaws developed into this strange beak," Olivier Rieppel, one of the researchers involved in the work, said in a statement. "It probably lived in shallow water and dug in the mud for food." As no such turtle has been described in the books of science, the animal has been classified as a completely new species. It has been named Eorhynchochelys sinensis, which means the ‘Dawn turtle with a beak from China’...

So the last book I read gave me a great review of the evolutionary history of tetrapods. One particular group of tetrapods that may or may not have represented the earliest amniotes (animals with more advanced egg membranes) were the Diadectomorpha.

Now, keep in mind that these were really primitive creatures in the lineage that eventually led to mammals. If you look at the skeleton of a Diadectes, for example, you'll notice that the spine has lumbar ribs, which suggests that it likely hadn't yet evolved a diaphragm, which helps with breathing when moving at high speeds.

But wait--what is that SKULL?

This is the most cartoonish skull I have ever seen! I mean, the poor guy looks like T. rex's dorky, uncool cousin.

Look, I know Diadectes lived before amniotes began to evolve fenestrae (holes) in their skulls to make great places to anchor tendons and muscles for stronger and wider bites. I still wouldn't want to get bitten by this critter, but the first thing I legitimately thought of when I first saw this photo was...

So from now on whenever I picture a life restoration of Diadectes in my head, this is what I'm going to see in my head:

Captorhinus skulls with pyrite and calcite crystal growth.

Captorhinus were anapsids from the Permian - meaning their skulls did not have the normal fenestration that diapsid reptiles or synapsid mammals have. Named for their hooked snout, these reptiles had a pineal(or "third") eye - a small photoreceptive spot on the top of the skull not seen in the pictures here.

Rare Metriorhynchus Crocodile Tooth Fossil, Jurassic Era, Oxford Clay, Bradley Fen, UK

Rare Metriorhynchus Crocodile Tooth Fossil – Jurassic Era, Callovian Stage, Oxford Clay, Bradley Fen, Whittlesey, Peterborough

This exceptional Metriorhynchus crocodile tooth fossil is a fascinating relic from the Callovian Stage of the Jurassic Period, approximately 166 to 163 million years ago. Discovered in the renowned Oxford Clay Formationat Bradley Fen, Whittlesey, Peterborough, this fossil offers a unique glimpse into the life of one of the Jurassic’s apex marine predators.

Metriorhynchus was a genus of marine crocodiles, uniquely adapted to a life in the ocean. Unlike their modern relatives, these crocodiles had streamlined bodies and paddle-like limbs, making them efficient swimmers. Their sharp, conical teeth were perfectly suited for catching fish, squid, and other marine prey. Fossils like this tooth are highly sought after for their scientific importance and connection to the ancient ecosystems of Jurassic Britain.

Features:

Species: Metriorhynchus (Marine crocodile)

Era: Jurassic (~166–163 million years ago)

Stage: Callovian

Formation: Oxford Clay Formation

Location: Bradley Fen, Whittlesey, Peterborough, UK

Paleontologists unveiled on Wednesday the fossil of a young marine crocodile dating back 10 to 12 million years that was discovered in a Peruvian desert. The fossil of the gharial—or fish-eating—crocodile, around three meters long (nearly 10 feet), was discovered late 2023 in perfect condition in Peru's Ocucaje desert, around 350 kilometers (190 miles) south of the capital Lima.

It’s a bird! It’s a plane! It’s… a dinosaur? Nope to all of the above. This Fossil Friday, let’s talk about pterosaurs—the first animals with bones to evolve powered flight. Though they were related to dinosaurs, pterosaurs evolved on a separate branch of the reptile family tree. They ruled the skies for more than 150 million years, evolving into dozens of different species. Some were as small as a paper airplane while others, like Pteranodon pictured here in the Museum's Hall of Late Dinosaurs circa 1940-1960, had a wingspan of more than 20 ft (6 m).

Along with other large pterosaurs, Pteranodon longiceps was first discovered in western Kansas, near a chalk formation called Monument Rocks. Today the region is dry, but at the time this species lived, about 85 million years ago, central North America was covered by a seaway. This large pterosaur likely spent its days flying over the sea. Unlike early species of pterosaurs, Pteranodon and many other Cretaceous-era species didn’t have any teeth. In fact, its genus name means “winged and toothless,” while the second name, longiceps, means “long-headed.”

Today, you can find Pteranodon in the Hall of Vertebrate Origins. We're open daily from 10 am-5:30 pm! Plan your visit.

Fossil predator is the oldest known animal with “saber teeth”

“Vaguely dog-like” animal was one of the oldest-known close cousins of modern mammals

The first true mammals evolved roughly 200 million years ago, during the early days of the dinosaurs. But mammals are the last surviving members of an older group, called the therapsids. At first glance, many therapsids weren’t obviously mammal-like , but they also had subtle features that we recognize in mammals today, like a hole on the sides of their skull for the jaw muscle to attach and structures on their jaw bones that would eventually evolve into mammals' distinctive middle ear bones. In a new paper in the journal Nature Communications, scientists announce the discovery of a fossil therapsid that’s the oldest of its kind, and maybe the oldest therapsid ever discovered: a vaguely dog-like saber-toothed predator.  The new fossil, which doesn’t have a species name yet, is a member of a group called the gorgonopsians. “Gorgonopsians are more closely related to mammals than they are to any other living animals,” says Ken Angielczyk, the Field Museum’s MacArthur Curator of Paleomammalogy in the Negaunee Integrative Research Center and a co-author of the paper. “They don’t have any modern descendents, and while they're not our direct ancestors, they're related to species that were our direct ancestors.”...
