Daily Dino Fact: Giraffe bird?

Hatzegotpteryx like WHOA

Q: Who’s the biggest flyer? – Gorgey
A: Gorgey, what a fantastic question! As we learned before, dinosaurs only walk on land so any flying or swimming reptile in the Mesozoic was not a dinosaur. The “flyers” were actually called pterosaurs, and they RULED the Mesozoic skies. Flying animals were not common during this era, and they pretty much dominated the air. Evidence has also shown that these creatures most likely were very skilled at walking on ground.
What I didn’t realize before researching this question is how stinkin’ big some pterosaurs became! Quetzalcoatlus and Hatzegopteryx were the two biggest pterosaurs of them all, and they lived during the Cretaceous up until the end. These two had wingspans of 40ft (12m) or more and were about the size of a giraffe. The biggest bird today is the Wandering Albatross, which has a wingspan of 12ft (3.7m). I can’t imagine what it would be like to see one of these monsters cruising through the sky.
The scary part is that paleontologists acknowledge that the fossil record of pterosaurs isn’t near complete, and it is possible that a fossil of a larger pterosaur exists somewhere in the earth… eep!

Daily Dino Fact: “I’m a real Triceratops!” No, you aren’t

The Pinocchio of Ceratopsians "I'm a REAL Triceratops!" No, no you're not

Q: What did the Ceratopsian Einiosaurus use its bizzare looking horns for? – Regisaurus

A: Great question Regisaurus! Before we get into the horns lets talk about little Einiosaurus here. I call him a little guy but he was a medium-sized Ceratopsian who grew to be about 20 ft (6m) long (Compare to Triceratops who grew up to 30 ft – 9m long). Still.. the funny proportions of his body make him look like a screwed-up Triceratops mini-me. Einiosaurus lived in the Late Cretaceous and fossils have been found almost exclusively in modern day Montana.

As for his horns… who really knows? Ceratopsians were all over the place. So many different species of random frills and horns and armor. Paleontologists are all over the place about what these could have actually been used for. Some say that maybe they weren’t even used for defense! Triceratops could easily have ripped in a hole into a large predator, but other ceratopsians have such strange horns that they couldn’t have been used to deal damage.

Others say they could have been used as a mating device, or a way to determine dominance in the herds. What do you think they were used for?
