Science Ask Us Anything What'Jurassic Park' got wrong about venomous dinosaurs And what did'Spinosaurus' really do with that sail? Dilophosaurus didn't have a frill or spit venom. Breakthroughs, discoveries, and DIY tips sent six days a week. We all know dinosaurs were scary. While not strictly a dinosaur, the ancient shark was four times longer than the biggest great white. Now, imagine one of those big bad dinos had venom. That'd be the last thing we need, but it very well could've been a reality. In a new episode of's Ask Us Anything podcast, we dig into the fossil record to see just how likely a venomous dinosaur would've been.

The leg bone uncovered in New Mexico belongs to an unusually large tyrannosaur--the group of dinosaurs that includes the mighty . The shinbone is three feet long and about five inches in diameter, only slightly smaller than the largest known specimen. The giant leg bone is detailed in a study published today in the journal .

New dinosaur discovered in Sahara desert was a horned'hell heron' 'Spinosaurus mirabilis' sported a 20-inch-tall'scimitar' on its head. Spinosaurus mirabilis stands along river's edge over its prey some 95 million years ago. A scimitar-shaped head crest and interdigitating teeth characterize this wading giant, one of the last-surviving spinosaurid species. Breakthroughs, discoveries, and DIY tips sent six days a week. Paleontologists still know comparatively little about fin-backed dinosaurs .

First discovered 20 years ago, the rare fossil combo reveals a Cretaceous meal in the making. Breakthroughs, discoveries, and DIY tips sent six days a week. A rare dinosaur fossil on display at the Museum of the Rockies in Bozeman, Montana, tells a gory story. The skull from a large plant-eating has a tooth lodged into it, indicating that it may have met its final moments as a meal. The tooth in question belongs to one of the most famous dinosaurs on earth-- .

All present-day birds are technically dinosaurs, but the 150-million-year-old, raven-sized hunter is the earliest known example of an avian animal. At the same time, lived during the Jurassic Period among multiple other feathered dinosaurs that were birds in the true sense of the term. But if it's any consolation, it's often still difficult for paleontologists to tell them apart, too.

Science Dinosaurs Teen discovers Australia's oldest dinosaur fossil--almost 70 years ago An early sauropodomorph likely made the 230-million-year-old footprint. Breakthroughs, discoveries, and DIY tips sent six days a week. In 1958, an Australian teenager named Bruce Runnegar uncovered a mysterious dinosaur footprint during a visit to a quarry with school friends. He kept the fossil for years, eventually becoming a paleontologist himself. Over six decades later, the prehistoric print is now ready for its close-up.

Breakthroughs, discoveries, and DIY tips sent six days a week. Approximately 290 million years ago, a carnivorous dinosaur stomping around present-day Germany had a tummy ache. The Paleozoic predator eventually vomited up its stomach contents, and then hopefully continued to live its best dino life. Unlike most ancient regurgitated meals, this particular mixture of half-eaten prey and digestive bacteria successfully fossilized into what's known as a regurgitalite. In 2021, paleontologists discovered the extremely rare find while working in the famous Bromacker Permian dig site, about 155 miles southwest of Berlin.

They're the first fossils found near Dinosaur National Monument in over 100 years. Breakthroughs, discoveries, and DIY tips sent six days a week. For a place named Dinosaur, it's been a while since the small Colorado town revealed any fossils . But after a 101 year lull in discoveries, work was paused on a new parking lot near Dinosaur National Monument, after construction crews uncovered a section of unexpected sandstone. Park staff and paleontologists soon examined the find, and identified sauropod bones most likely belonging to --a massive, long-necked dinosaur from the Late Jurassic period .

New analysis of bone growth rings shows the'tyrant lizard king' grew very slowly. Breakthroughs, discoveries, and DIY tips sent six days a week. Based on the annual growth rings (like those on trees) within fossilized leg bones, scientists estimate that usually reach adulthood at around 25 years old. However, new research argues that their growth phase lasted significantly longer. They may have become fully grown--approximately eight tons--after 40 years.

The tiny insects are older than dinosaurs. Breakthroughs, discoveries, and DIY tips sent every weekday. Not eating yellow snow is obviously wise advice, but how about snow that looks like a poppy seed bagel? You should also avoid that too, because those "seeds" may actually be tiny critters commonly called snow fleas. As a video taken at the Monomoy National Wildlife Refuge in Massachusetts shows, these little black specks bounce across the snow.
