#OnThisDay in 1969, the dromaeosaur Deinonychus was named.

This theropod lived in the Early Cretaceous in what is now the U.S., and its discovery changed the way paleontologists thought about #dinosaurs

It had a small body, large claws on its feet, blade-like teeth, and was agile. It may have also been covered in feathers

#OnThisDay in 1995, the film Carnosaur 2 was released (direct-to-video).

It’s an action horror film, where a team of scientists go investigate a possible meltdown at a uranium mine and found lots of cloned #dinosaurs 

Dinosaurs in the movie include Velociraptor and Tyrannosaurus rex. (Sounds pretty similar to #JurassicPark)

#OnThisDay in 1824, the first non-avian #dinosaur Megalosaurus was named (happy 200th anniversary!)

#Megalosaurus was a carnivorous dino that lived in the Jurassic in what is now England, and its name means “great lizard”

What we know about Megalosaurus was changed a lot in the last 200 years. You can how Meglaosaurus was first reconstructed at Crystal Palace Park: bulky and on four legs with a dragging tail. Today we know it walked on two strong legs, kept its balance with its tail, and overall was robust

#OnThisDay in 1928, paleontologist John Ostrom was born. Ostrom inspired the #Dinosaur Renaissance, after he discovered Deinonychus in 1964 and argued that dinosaurs could be fast moving and warm-blooded He also helped show that birds are dinosaurs (an idea that had been floating around a while but wasn’t always accepted), and suggested that the duck billed dinosaurs (hadrosaurs) had a good sense of smell with their long nasal passages that wound around the skull

#OnThisDay in 2017, Arkansaurus became the state #dinosaur of Arkansas. The first fossils were found in 1972, but it took until 2018 to be officially named Arkansaurus (yes it got its name after it became the state dinosaur—the name had been in the works for a while) Arkansaurus was an ornithomimosaur, so it had a long neck, ran on two legs, and had a small skull

#OnThisDay in 2023, we learned more about what #dinosaurs sounded like, specifically the ankylosaur Pinacosaurus Pinacosaurus had a club tail and was covered in armor, and scientists found its fossilized voice box (the larynx) So what did we learn? This dinosaur’s voice box probably worked as a sound modifier like birds. So maybe it made lots of sounds, like grunts, roars, or bellows.

#OnThisDay …It's Valentine’s Day! What does that have to do with #dinosaurs? Well, there are multiple poems about birds mating on St. Valentine’s Day (and birds are dinosaurs) Geoffrey Chaucer wrote the Parliament of Fowls in 1382, where birds come together to find their mates. The poem was for the feast day of St. Valentine of Genoa, which was May 3, but today of course we celebrate love and Valentines on February 14 Geoffrey Chaucer, Genoa, Phil, Poems, Valentines Day, Wikimedia Commons, Valentine's Day Diy, Poetry
