This theory is called catastrophism.

Geology. a basic law of geochronology, stating that in any undisturbed sequence of rocks deposited in layers, the youngest layer is on top and the oldest on bottom, each layer being younger than the one beneath it and older than the one above it.

As a result, rocks that are otherwise similar, but are now separated by a valley or other erosional feature, can be assumed to be originally continuous.]]> 2018-01-23 20:27:42 UTC https://padlet.com/3043821/pnu9q2skipd8/wish/224003643 3043821 https://padlet.com/3043821/pnu9q2skipd8/wish/224004736 Cross-cutting relationships is a principle of geology that states that the geologic feature which cutsanother is the younger of the two features.

Most fossils do not contain actual body parts but are impressions, molds or casts of the original organism.

Many fossil trackways were made by dinosaurs, early tetrapods, and other quadrupeds and bipeds on land. Marine organisms also made many ancient trackways (such as the trails of trilobites and eurypterids like Hibbertopterus]]> 2018-01-23 20:36:15 UTC https://padlet.com/3043821/pnu9q2skipd8/wish/224007342 3043821 https://padlet.com/3043821/pnu9q2skipd8/wish/224007812 A coprolite is fossilized feces. Coprolites are classified as trace fossils as opposed to body fossils, as they give evidence for the animal's behaviour (in this case, diet) rather than morphology. ]]> 2018-01-23 20:37:24 UTC https://padlet.com/3043821/pnu9q2skipd8/wish/224007812
