caption_attribution_description: English: Fossilized skeletons of two adult male Diictodon that crawled into an underground burrow and curled-up together probably to conserve heat during winter hibernation. It has been proven that in this species only mature males grow tusks as a sexual signal. In this instance a sudden flood event or possible a roof collapse killed and buried them before they could be roused from their cold-induced slumber
context_page_description: Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks, burrows, cast-off parts, fossilised feces, palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science.
