When Dinosaurs Roamed in Attleboro

Some cool science news…

NORTH ATTLEBORO, Massachusetts (Reuters) – U.S. researchers say they have discovered what appears to be the oldest imprint of a prehistoric insect, made while the dragonfly-like creature was still alive.

The imprint found at a rocky outcrop near a large shopping center in North Attleboro, Massachusetts, is believed to have been made by an insect about three inches long as it stood on mud some 312 million years ago.

  1. This of ourse is one of those interesting non-stories that pass through a rather coarse substance filter now and then. What is a kind of interesting “find” in a place not known for very significant fossil discoveries, somehow assumes an aura of significance much beyond reality. If the date of 312 million years is correct (why not 300, or 320, or 340?)the fossil impression (it seems to be a partial body mold and not the actual remains of the organism) is in rock of Pensylvanian age (geological jargon, I know). Insects including dragon flies and giant roaches (an exterminator’s dream) first appear in much older Devonian Period rocks in many parts of the world, rocks that were deposited between 410 and 360 million years ago. The group to which insects belong, the arthropods, have a very much earlier beginning in the oceans of more than 550 million years ago. It is true that the earliest reptiles appear in Pennsylvanian age rocks, but the amphibians still remained a dominant group of vertebrates for some time. The first dinosaurs do not appear until much later, perhaps 230 million years ago.
