Here's even more silliness. Evolutionists claim these fossils that they find are in layers such as the following. They'll say in a deep voice trying to act intelligent,
"For example, the Cambrian layer contains trilobite fossils, which the evolutionists believe lived during the Cambrian period from 544 to 510 million years ago. The Devonian layer contains certain fish fossils, which evolutionists believe lived during the Devonian period from 409 to 363 million years ago. The Jurassic layer contains certain dinosaur fossils which the evolutionists believe existed during the Jurassic period 202 to 141 million years ago.
What they don't tell you is these layers such as Cambrian, Devonian and Jurassic refer to location and not time. That is what these layers were named after.
Here's what people like Jose Fly will tell you, "About 400 million years ago, a group of fishes called lobefins appeared, probably in fresh water. Lobefins had two important pre-adaptations to land-life: stout, fleshy fins with which they crawled about on the bottoms of shallow, quiet waters and a outpoaching of the digestive tract that could be filled with air, like a primitive lung. The coelacanth seen in Figure 24-33d is a lobefin that was believed to be long extinct before its discovery in 1939." 1

When creation scientists studied the coelacanth, their lungs were used for buoyancy. It didn't have anything to do with breathing.
This is the kind of thing that's really hilarious, Professor Fly.
