Megalodontidna školjka

**Megalodontidna školjka** Megalodontidne školjke se najpogosteje ohranijo kot kamena jedra. Njihova oblika in velikost pomagata paleontologom razkriti tudi starost kamnin, v katerih so odkrite. V Sloveniji njihove ostanke najdemo le v zgornjetriasnih dolomitih in apnencih, kjer so opazni značilni prerezi megalodontid.

Their shapes and sizes help paleontologists to establish the age of the rocks in which they are found. In Slovenia, their remains are found only in the Upper Triassic dolomites and limestones, where characteristic cross sections of megalodontides are clearly seen.
