This new discovery could change the way we study dinosaurs

Despite everything fossils can tell us about dinosaurs, a new study is changing some of the oldest research we have at our disposal. The study in question, published in the journal Nature today, not only changes how some dinosaurs are classified, but also suggests traits of a common ancestor and shakes up what we thought we knew about where dinosaurs came from.

Rare dinosaur egg embryo hints at 6-month incubation times

Rare dinosaur egg embryo hints at 6-month incubation times

The popular image of dinosaurs is that of giant lizards. After all, that's where their name came from. Science, however, paints us a different and more complicated story. They were warm-blooded, unlike reptiles and some were actually closer to birds than lizards, having feathers and wings. There were, however, nonavian dinosaurs that were indeed closer to crocodiles than chicken. And these, according to scientists, laid eggs that took 6 months or more to hatch, which, in a sad way, helped bring about their extinction.

This odd dinosaur changed drastically as it aged

This odd dinosaur changed drastically as it aged

In the Gobi desert a new sort of dinosaur has been discovered which changed drastically from birth to age six. Using a total of 19 sets of bones, paleontologists show how Limusaurus inextricabilis ("mire lizard who could not escape") changed in big ways in the first year of its life. Researchers have shown how baby versions of this dinosaur had teeth, but that these teeth left the dinosaur within a year. But what about reptiles in our modern age that lose and grow several sets of teeth? This research has an answer for that, and other oddities, too.

Feathered dinosaur tail found in Amber is the first of its kind discovered

Feathered dinosaur tail found in Amber is the first of its kind discovered

The chunk of amber seen in the first photo here is something very unique and unusual. It holds a segment of a feathered tail from a Cretaceous-era dinosaur along with an ant and various plant segments and other debris. The tail is the big draw though as it is the very first of its sort ever discovered.

Dinosaur Games: Mud Dragon strikes out in ancient pit

Dinosaur Games: Mud Dragon strikes out in ancient pit

Tongtianlong limosus, the Mud Dragon, was caught in sticky mud in China over 66 million years ago - and died there. Of course it wasn't called China back then, and this was when our planet looked a lot different from what it looks like today. But back between 66 and 72 million years ago, the Mud Dragon gasped its last. Not long after the death of the Mud Dragon, our Earth changed drastically.

Scientists discover first known fossil of dinosaur brain tissue

Scientists discover first known fossil of dinosaur brain tissue

What you see above might not look like much more than a small rock, but it marks a huge first in the field of paleontology: it's the first known example of a dinosaur brain tissue fossil. Originally discovered in Sussex, UK, it's believed to have come from a species similar to the Iguanodon, a large herbivore, roughly 133 million years ago.

New dinosaur species Savannasaurus discovered in Australia

New dinosaur species Savannasaurus discovered in Australia

Back in 2005, researchers found dinosaur bones in Queensland, Australia, and now many years later there's more information about them: they belong to a newly discovered dinosaur species dubbed Savannasaurus elliottorum, a type of long-necked dino called a sauropod. The fossilized remains are notable for many reasons, one being that it’s the most complete sauropod skeleton ever found in the land down under. And, of course, there’s that part about it being a whole new species.

Study aims to determine if ancient dinosaurs really could roar

Study aims to determine if ancient dinosaurs really could roar

Thanks to movies like Jurassic Park we all think of dinosaurs as having incredibly loud roars. Scientists aren't sure if the actual dinosaurs that these movies aim to represent could roar. The reason for this is that it is incredibly hard to find ancient dinosaur voice boxes because they didn't fossilize well. What dinosaurs would have used to make vocalizations would have been one of two different structures called a larynx or a syrinx. Most living land-dwelling vertebrates today use a larynx to vocalize, this is a structure mostly made of cartilage that makes sounds at the back of the mouth.

Fossilized dinosaur footprint sets record with massive 3.5ft length

Fossilized dinosaur footprint sets record with massive 3.5ft length

Researchers have discovered one of the largest fossilized dinosaur footprints in existence, with it measuring about 42-inches in length and 30-inches in width. The discovery was made in Mongolia’s Gobi Desert by researchers from Mongolian and Japanese institutions who were on a joint project. According to these researchers, the footprint may have come from a herbivorous long-necked titanosaur, a massive dinosaur that may have been more than sixty feet tall and nearly one hundred feet long.

Dinosaur-age bird wing discovered in amber jewelry market

Dinosaur-age bird wing discovered in amber jewelry market

Bird skin, claws, muscle, and feathers have been discovered in amber dated to nearly a hundred million years ago. Researchers suggest that these bits and pieces of birds show how coloring and arrangement of bird feathers has remained largely the same for a very, very long time. Wing tips is what they have. A very strange (but apparently not entirely uncommon) origin story is what they've got to tell.

New reptile species discovered with 250 million year old fossil

New reptile species discovered with 250 million year old fossil

A team of scientists have discovered a fossilized reptile skull dating back 250 million years, revealing not only evidence of a new species, but connections to the origins of dinosaurs as well. The skull, found by paleontologists from universities in Brazil and the UK, is well-preserved and features a number of serrated teeth, and is said to have survived a mass extinction event that occurred roughly 252 million years ago, eradicating 90% of life on Earth.

Study finds that dinosaurs may have evolved much faster than previously thought

Study finds that dinosaurs may have evolved much faster than previously thought

To understand our world and its future, we often must look to the past. Clues about the evolution of the planet and its inhabitants are scattered in the ground, which helps unlock the mysteries about the past. Unfortunately, sometimes deciphering those clues can be difficult, and the smallest error in calculations can put the dates of events off by millions of years, as one group of researchers recently found.
