A new sculpture and an upcoming restoration are breathing life into the Crystal Palace Dinosaurs, one of 19th-century Britain’s most curious creations

An ancient bison gets stuck in a tar pit as a fire burns nearby in this illustration. A warmer and drier climate could have made Southern California vulnerable to human-caused fires at the time, the new study suggests.

Human-Caused Fires and a Changing Climate May Have Contributed to Mass Extinction 13,000 Years Ago

The deadly combination likely led several species to disappear from Southern California during the late Pleistocene

This Massive Extinct Whale May Be the Heaviest Animal That Ever Lived

The newly discovered behemoth could unseat the blue whale for the title, but scientists can only make educated guesses about its weight

Scientists Find the 'Extinct' Victorian Earless Dragon, Not Seen Since 1969

Once thought to be gone from the wild, the lizards will now enter a breeding program in an attempt to save them from the brink of extinction

The massive sharks known as megalodons ruled the oceans for some 20 million years.

Megalodons Were Warm-Blooded—and It Was a Blessing and a Curse

The giant sharks likely warmed some of their body parts, helping them grow massive but leaving them vulnerable to environmental changes, a new study finds

During the 'Great Dying,' This Saber-Toothed Predator Reigned

This ancestor of mammals briefly thrived amid a massive extinction event, hinting at how carnivores may respond to climate change today

Mammoth and elephant tusks are elongated incisors, so they're made of the same materials as other teeth.

Male Woolly Mammoths Had Testosterone-Fueled Aggressive Episodes

By studying preserved tusks, scientists suggest the mammals experienced a yearly condition known as musth, like male elephants do today

Now extinct, thylacines are carnivorous marsupials that once roamed freely around Australia, Tasmania and New Guinea.

Extinct Tasmanian Tigers May Have Survived Longer Than Previously Thought

Though the last documented thylacine died in 1936, a new study based on alleged sightings suggests the species lived for decades more

The meatball made with woolly mammoth DNA was unveiled at a museum in the Netherlands this week.

This Massive Meatball Was Made With Woolly Mammoth DNA

Meant to be more sustainable than animal meat, this lab-grown alternative might offer a glimpse into the future of food production

Many of the reptiles that thrived during the Triassic were crocodile relatives that dinosaurs would later mimic through evolutionary happenstance, such as Postosuchus (back) and Desmatosuchus (front).

Dinosaurs Were Evolutionary Copycats of These Long-Lost Look-Alikes

Before T. rex and ankylosaurus ruled the Earth, a host of similar Triassic reptiles reigned

The dodo, now extinct, weighed about 50 pounds, had blue and grey feathers and couldn't fly.

This Company Wants to Bring the Dodo Back From Extinction

Colossal Biosciences plans to de-extinct the dodo, but some scientists question whether it’s ethical—or even plausible

Tyrannosaur fossils show the animals squared off and bit each other in the face.

Busted and Broken Fossils Show How Dinosaurs Fought

From locking horns to biting each other in the face, this is how dinos of the same species battled

The year was filled with major discoveries about a number of species.
