Imprints or impressions of such things as footprints or trails are generally referred to as trace fossils. Body impressions are called mold fossils, and molds that are filled in are called cast fossils.
Trace fossils are things like foot prints, burrows, and fossilized feces (coprolites). So quite simply, they're formed by the living-part of an animal's life (rather than its death, being buried as a body fossil). If there's a muddy bottom and an animal crawls across it, it could leave an imprint. Burrows could left behind. These divots and so on can get filled in with hardy sediment that becomes fossilized when the mud is covered over and the sediments become a standard sedimentary rock containing trace fossils.
A fossil created by a print or impression is called an imprint fossil. Imprint fossils are formed when an organism's remains leave an impression in sediment that hardens over time. This process captures the shape or texture of the organism, providing valuable information about ancient life forms.
At the stage of development when the gut forms there is only a single opening into the digestive track, this opening may become either the mouth or anus. In the echinoderms, chordates, and hemichordates the blastopore becomes the anus and a new opening forms the mouth, these are called deuterostomes
Polymers are formed from monomers.

An imprint fossil is formed when an animal or plant makes a print in the soil. Such as a footprint.

Trace fossils are formed when an organism leaves a trace; such as a footprint, a bite mark, or even poo.

An imprint of a cactus leaf was formed in a fossilized state, often found in sedimentary rock layers where the conditions allowed for the preservation of organic material. This process typically occurs in arid or semi-arid environments, where the leaves could be buried quickly by sediment, preventing decomposition. Over time, minerals infiltrate the leaf's structure, creating a lasting imprint that can be studied by paleobotanists to understand ancient ecosystems. Such fossil imprints provide valuable insights into the vegetation and climate of the past.
