The gang discusses two papers that look at the body size of ancient animals. The first paper uses new metrics to estimate the size of the ancient fish Dunkleosteus, and the second paper looks at the various ways that theropod dinosaurs can get big or small. Meanwhile, Amanda is 10 minutes away from being taken to Oz, Curt invents a new adaptation, James figures out perpetual energy, and everyone is forced to record over a conference call.
Up-Goer Five (Amanda Edition):
Today our friends talk about a large animal that lives in water with no legs but a big mouth and moving mouth pieces and a hard outer cover. This big animal was one with a hard part in its back that ate lots of things very early before many other things with hard parts in its back were around that ate other things. People used to think that it got very very very big but this study uses numbers to show that it was actually not as big as people used to think. The numbers are very good and are probably going to be very good for lots of animals that live in water with no legs.
The second paper looks at large angry animals with no hair and big teeth that lived a long time ago, but not as long ago as the large animal that lives in water with no legs and a big mouth and moving mouth pieces. It looks at how the hard pieces of these large angry animals with no hair and big teeth grew to see how they got big or small, because some got very big and some got very small. It turns out that the ones that got big did it in some different ways, and the ones that got small did it in some different ways, which is very cool.
