GENERAL GEOLOGY

Detailed explanation-1: -A trace fossil is a result of animal activity. For example, a dinosaur footprint or an arthropod burrow would be an example of a trace fossil.

Detailed explanation-2: -Dinosaur footprints and worm burrows are examples of trace fossils, as are coprolites (fossilized dung or feces). In the kits, the coprolite (1), theropod track (17), and synapsid track (18) are trace fossils.

Detailed explanation-3: -Examples of trace fossils are tracks, trails, burrows, borings, gnawings, eggs, nests, gizzard stones, and dung.

Detailed explanation-4: -The tracks are located on a public beach in Penarth, Wales and are thought to date back over 200 million years. Hudson and Lomax were able to study the footprint in detail once it was relocated, which enabled the researchers to learn more about the dinosaur who left the impression behind.

Detailed explanation-5: -Dinosaur footprints are found only in sedimentary rocks, which are formed through the deposition and solidification of sediments, or particles, transported by water, ice, and wind. The tracks in the Connecticut River Valley are in sandstone, initially fine sand-sized sediment.
