Dinosaurs, Geology and Trace Fossils 4 Todd Lizotte – Copyright 2020 Connecticut River Valley / Triassic Period

Within what is now the Connecticut River Valley, around 200 million years ago, the area was a swampy, semi tropical – warm and humid / located just North of the equator. Dinosaurs similar to Dilophosaurus and other reptiles and amphibians occupied the shores, during the Triassic Period of the Mesozoic Era.

At this time the Super Continent Pangea is soon to split and the Atlantic ocean will form further, to what we know today. Dinosaurs, Geology and Trace Fossils 5 Todd Lizotte – Copyright 2020 Connecticut River Valley Historically

Edward Hitchcock, pioneer of North American dinosaur footprint studies (My 1793-Feb 1864)

The Pratt Museum of Amherst College in Amherst, Massachusetts contains the largest dinosaur footprint collection in the world, largely amassed by Edward Hitchcock in the years from 1836 to 1865.

Typical dinosaur types that are considered are: Dilophosaurus: “duh·laa·fuh·saw·ruhs” Coelophysis: “See-low-fy-sis”

Dinosaurs, Geology and Trace Fossils 7 Todd Lizotte – Copyright 2020 What is Ichnology or an Ichnologist?

Ichnologist is one who studies trace fossils. A trace fossil, also ichnofossil, is a fossil record of biological activity but not the preserved remains of the plant or animal itself. Trace fossils contrast with body fossils, which are the fossilized remains of parts of organisms' bodies, usually altered by later chemical activity or mineralization.

You are a paleontologist who has come across these trace fossils. Now your job is to figure out what happened here.

• Who made the footprints? • What do the ‘creatures’ look like? • What were they doing? • What happened?
