26 Dinosaur Facts That Are So Absolutely Bonkers I’m Questioning My Entire Education RN

After speaking with paleontologist Dr. Kenneth Lacovara, I can honestly say — I didn’t know as much as I thought! I mean, did you know dinosaurs likely didn’t roar or that they still have living descendants today? What about the actual size of a velociraptor? There’s more, too. From the speed of a T-Rex to a pterosaur’s extensive wingspan, here are more fascinating dinosaur facts you probably didn’t know.

For context, Dr. Lacovara has discovered some of Earth’s largest dinosaurs, including the massive Dreadnoughtus from Jurassic World — he even consulted on early Jurassic films. This interview was conducted during a press trip to Mantua, New Jersey, to tour Edelman Fossil Park & Museum, which Dr. Lacovara founded and opened on March 29. It has been edited for length and clarity.
