Birds are tiny dinosaurs. In fact, many scientists have altered the classification of vertebrates. In the past there were 5 main groups, Fish, Amphibians, Reptiles, Birds and Mammals. Dinosaurs were originally classified under Reptiles. However, we have figured out that dinosaurs were as different from reptiles as mammals are, so they should be in their own group. Not only that, but birds evolved form dinosaurs, so the new classes are Fish, Amphibians, Reptiles, Dinosaurs and Mammals. Just watch a cassowary attack something, or a rooster as it struts around and you definitely see the family resemblance.

WoodrowSkillson posted:its ok ones the size of the raptors from jurassic park existed http://en.wikipedia.org/wiki/Deinonychus Actually, Deinonychus was only about hip-high at the hips (human to Deinonychus), and weighed no more than 100 pounds or so. However, there was a dinosaur like those in Jurassic Park. That was Utahraptor Ostrommaysorum (named after John Ostrom, the discoverer of Deinonychus. fun fact, when Jurassic Park was being filmed, several paleontologists complained, because they were making the raptors so large, when none of that size had been discovered. Then, during filming, a specimen was discovered of Utahraptor and Spielberg held this up as justification, even though he used the wrong name...

concerned mom posted:Genesplicer would ornithicians and saurischians have been classed as separate classes if they hadn't been grouped together originally or is the classification more based on ankle bones and other stuff? I think that the pelvis is more fundamental, and therefore provides a better demarcation than most other ways we could divide them. Do we really need to divide them? Maybe not, but I'm a splitter, not a lumper. I like lots of groups.

Robo Reagan posted:Exciting and cool movie The book has regular-sized Velociraptors. Small (About the size of turkeys), but possibly pack-hunters. Much creepier, in my opinion.
