GEOL 104 Dinosaurs: A Natural History

Fall Semester 2000
Dinosaur Science in Jurassic Park and The Lost World

The procedure to resurrect non-avian dinosaurs, according to JP and TLW:

How feasible is this?

DNA is a fragile molecule: will break down over time on its own accord

Blood is a complex food: most blood suckers inject digestive enzymes into victim when they eat, so blood is digesting PRIOR to feeding (which is why such bites itch!!).

How would you establish that the blood in the blood sucker was dinosaurian (much less what species)?

DNA is packed with information; closely related taxa have VERY similar DNA sequences:

Why use frog DNA? (Plot reasons: wanted to include the ability to change sexes and breed in the novel)

In reality, bird DNA would be closest to those of other dinosaurs, then crocodilians, then lepidosaurs, then turtles, then mammals, and only then amphibians.

Even if you had complete genome and some how cloned the dinosaur, still would be problems:

However, SOME possibility DNA fragments might survive in the fossil record.

If so, may be informative:

Time permitting we will watch videos of the various dinos in JP and TLW.
