Don't want to cross paths with any of these creatures.

RE: Paleo story of the week
Speaking of fearsome creatures...as many of you know I spend a lot of time under the sea (sounds funny when I write that, under the surface of the sea?, underwater?) anyway, paleontologists have recently discovered the remains of an ancient ocean denizen described thus "Pliosaurus funkei had a bite four times as powerful as Tyrannosaurus rex". "They had teeth that would have made a T. rex whimper."

Take a look at the artist renderings and tell me you'd dip your toe at the beach if these animals were still around.

Didn't think so Shocking

PS Notice how clever God/Satan is by hiding these fake monster bones in Svalbard, Norway, a string of islands located between the European continent and the North Pole! Makes it appear as though the earth was truly more than 6000 years old! What sneaky bastards. Cool

How did dinosaurs do the naughty? Not as straight-forward as one might imagine.

Loss of the bony tail and development of hind limbs, may have contributed more to the early diversification of birds than flight. Thumbsup

That makes sense considering a bird's tendency to run rather than fly.

What is going to happen to life as the Earth's climate transitions? Looking at the Eocene extinctions associated with the transition from Greenhouse to Icehouse climate, may provide some perspective.

Turtle shells are actually turtle ribs (which is nothing new) and developed from endoskeletal elements of its ancestor. This information about the evolutionary origin of the shell/carapace is important for better understanding its relation to other reptiles and the dinosaurs. Chiefly that it is not as closely related to the ancestral/primitive reptile and is instead, more closely related to dinosaurs and alligators.

Also worthy of note (although I don't have studies to link for this) is that turtles/tortoises are very interesting as to how they evolved. They are a group we know has gone from water to land and back to water and some went back to land again. That is very intriguing for development of organs and limbs. For comparison, this would be like a dolphin transitioning back to land (although mammals didn't evolve in water, this would mean going back to the tetrapod roots in order to make the comparison to turtles which have transitioned back and forth more than once as a group).

One more, I'm excitable this morning.

Why did the ray-finned fishes not produce the ancestral tetrapod? It has to do with how stress is distributed across the bones.

Yep lobe-finned fishes and their descendants were able to develop stronger bones, resulting in precursors to arm and shoulder bones - radius, ulna, humerus, the lot.

Really cool thing is from Acanthostega to Panderichthys to Icthyostega to Tiktaalik, we've got fantastic examples of each step along the way.
