Hi Chico
Today is our last day on Apatosaurus Island in DITT. The second pic shows the allosaurus in all his glory. He was the biggest meat eating dino in the Jurassic. Can you see the tail of the apatosaur above him? Do you think he hunted them? Here's a hint: an animal usually kills what it can eat in a few days at most. That's the apatosaur's tail! We think that unless the allosaur hunted in packs, the adult apatosaur and the other titanosaurs were safe from attack. That's a pretty neat defense, getting so big that nothing will attack you. Are there plant eaters today who do the same? Sure, elephants, rhinos, hippos to name some. Of course in any extinction event it's the titans, the megafauna, who die first, because they can't adjust to changing conditions or food sources fast enough to survive. Okay, the first pic in my gallery is a close up of the allosaurus's chest. Do you see a v shaped bone? You have one of those, and so do I, it's a wishbone! The scientific name is furcula, and 2 legged meat eaters all had those. We are narrowing down our ancestors, did you notice?
Oh, one last word about the sauropods on 4 legs: remember that all dinos started out bipedal? Well, these guys probably dropped to 4 legs for more equal weight distribution and to maximize food sources. Thanks again for your support, see you tomorrow with another hug, blog, and vote. Gizmo |
