WebPelycodus (from Ancient Greek πέλυξ (pélux), “bowl” + ὀδούς (odoús), “tooth”) is an extinct genus of adapiform primate that lived during the early Eocene period in Europe and North America, particularly Wyoming and New Mexico. It is very closely related to Cantius and may even be its subgenus. It may also have given rise to the Middle Eocene Uintan primate … WebHowever, stratophenetic series represent multiscale geological and biological interactions, defying simple analysis and interpretation. A numerical model is presented that simulates stratophenetic series in shallow marine siliciclastic deposits.

For example, Banner & Blow (1960, 1965) considered T. quadrilobatus ancestral to the other T. sacculifer plexus morphospecies, whereas Kennett & Srinivasan (1983) regarded T. trilobus as ancestral to the others.
