Boreosomus is, in the strict sense, a marine fish known in great detail from the lower Triassic of Greenland, Spitzbergen, and Madagascar. The myalinids were collected from beds near the top of the unit about 1 mile east of the Hotshot prospect (pl. 1, sheet 2).

Triassic Period - Triassic Period - Terrestrial reptiles and the first mammals: On land the vertebrates are represented in the Triassic by labyrinthodont amphibians and reptiles, the latter consisting of cotylosaurs, therapsids, eosuchians, thecodontians, and protorosaurs. All these tetrapod groups suffered a sharp reduction in diversity at the close of the Permian; 75 percent of the early.

These subcontinents lay centered at 30°N, and on the Equator, respectively.
