    This amber nugget from Myanmar holds the first known baby snake fossil

    The first known fossil remains of a baby snake have turned up in a hunk of amber found in Myanmar. The critter, a new species named Xiaophis myanmarensis, met its untimely demise about 99 million years ago, during the Cretaceous Period, an international team of researchers reports July 18 in Science Advances.

    How do we know it’s a baby?

    First, it’s tiny. The skeleton, which is missing its...

    Oldest known lizard fossil pushes group’s origins back 75 million years

    A little animal that washed out to sea 240 million years ago off the coast of what’s now Italy turns out to be the oldest known fossil of a lizard.

    The identification pushes back the fossil record of snakes and lizards by about 75 million years, says Tiago Simões of the University of Alberta in Edmonton, Canada. He and colleagues used observations of the fossil, called Megachirella...

    Fossil shows that ancient reptile gave live birth

    A prehistoric marine reptile may have given birth to its young alive.

    A fossil from South China may be the first evidence of live birth in the animal group Archosauromorpha, scientists report February 14 in Nature Communications. Today Archosauromorpha is represented by birds and crocodiles — which both lay eggs.

    Whether this fossil really is the first evidence of live birth in...

    Dinosaurs may have used color as camouflage

    The stories of dinosaurs’ lives may be written in fossilized pigments, but scientists are still wrangling over how to read them.

    In September, paleontologists deduced a dinosaur’s habitat from remnants of melanosomes, pigment structures in the skin. Psittacosaurus, a speckled dinosaur about the size of a golden retriever, had a camouflaging pattern that may have helped it hide in forests...

    Snakes evolved from burrowing ancestor, new data suggest

    View the video

    The mother of all snakes got its start underground.

    X-ray images of snake and lizard skulls suggest that modern snakes’ ancestors burrowed rather than swam, scientists report November 27 in Science Advances.

    The study is the latest to suggest that snakes evolved from land lizards that lost their limbs while adapting to a slithery, subterranean lifestyle (SN: 8/...

    Museum fossil links snakes to lizards

    View slideshow

    The worldwide hunt for a fossil link between snakes and lizards has succeeded — in a museum.

    The fossil, of a four-legged snake, hints that the ancestors of modern-day snakes may have evolved on land rather than at sea, researchers report in the July 24 Science. It’s the first four-legged snake fossil ever discovered, bridging the gap between snakes and lizards, says...

    Snakes crawled among Jurassic dinosaurs, new timeline says

    Just call it the Jura-sssss-ic Period. Newly identified fossils suggest that snakes slithered through much of the golden age of the dinosaurs, a finding that pushes back the fossil record for snakes by 70 million years.

    Ancient skulls with features similar to modern snakes tipped paleontologists off to the new timeline, they report January 27 in Nature Communications.
