NH Notes: Fossilized Animal Burrows in Argentina

Fossilized bones of dinosaurs, whales and mammoths get all of the attention but trace fossils provide important evidence for interpreting when and how organisms lived on Earth in the past. Trace fossils are not the fossilized remains of organisms themselves but rather are evidence of the past presence of organisms.  The most recognizable trace fossils... Continue Reading →

Geological Context II: Neanderthals and the Italian Supervolcano

There are thousands of sites with either human remains or artifacts (stone tools usually) that are known across southern Europe and many are found in locations where they are found in layers stacked on top of each other like in caves or flood plain locations along rivers. But, the exact pattern of Neanderthal and modern human population migrations and changes is not my main interest.

Giant Dino Eggs Found? Bad Reporting on Bad Science

Dinosaur eggs are surprisingly (to the non-biologist) similar in size. Even the very largest dinosaurs laid eggs that were hardly any bigger than the largest eggs found today. These are observations from the fossil record and these observation make sense biologically even though all we see are fossilized eggs. Eggs are limited in the size they attain for several reasons but one of the most important is that the embryos in the eggs must have oxygen to grow.

The Lost World Of New York: Another Ancient Forest Reconstruction

A quick note about another report of a fossilized forest that has been described. Last week it was PNAS that had the big story of a the "Permian Pompeii," a fossil forest reconstructed in China which I discussed in "An Ancient and Alien Forest Reconstructed." Not more than a week later the magazine "Nature" is highlighting the description of a another reconstructed forest.
