Palaeocene map (adapted from Ron Blakey). Red marks the North American faunal province, dominated by ptilodontoideans, microcosmodontids, eucosmodontids, taeniolabidids, meniscoessids, ferugliotheriids and relictual therians; gold marks the Antarctic faunal province dominated by dryolestoids, sudamericids, greniodontids, ferugliotheriids, monotremes and a few northern immigrants like ptilodontoideans; yellow marks the Afro-Arabian faunal province dominated by galulatheriids and kogaionids with perhaps relictual therians; green marks the Indo-Malagasy faunal province dominated by kogaionids, adalatheriids, sudamericids and relictual therians; orange marks the European faunal province dominated by boffiids, eucosmodontids, microcosmodontids, ptilodontoideans, taeniolabidids, meniscoessids, kogaionids and relictual therians; and purple marks the Asian faunal province, dominated by lambdopsalids, taeniolabidids, ptilodontoideans, boffiids, eucosmodontids, meniscoessids and microcosmodontids.

Red marks the North American faunal province, dominated by ptilodontoideans, microcosmodontids, eucosmodontids, ferugliotheriids, taeniolabidids, lambdopsalids and adalatheriids; orange marks the European faunal province, dominated by taeniolabidids, ferugliotheriids, boffiids, ptilodontoideans, eucosmodontids, microcosmodontids and galulatheriids; burgundy marks the Balkanatolian faunal province, dominated by kogaionids, meniscoessids and galulatheriids; lime marks the Afro-Arabian faunal province, dominated by kogaionids, galulatheriids, afroptilodontoideans and boffiids; green marks the Malagasy faunal province, dominated by kogaionids, afroptilodontoideans, boffiids, adalatheriids and sudamericids; purple marks the Asian faunal province, dominated by sudamericids, adalatheriids, lambdopsalids, eucosmodontids, ptilodontoideans, kogaionids and microcosmodontids; black marks the Antarctic/Australian faunal province, dominated by dryolestoids, monotremes, sudamericids, ferugliotheriids and greniodontids; yellow marks the South American faunal province, similar to the latter but with recent galulatheriid, afroptilodontoidean and boffiid arrivals.

Oligocene map (adapted from Ron Blakey). Red marks the Pan-Arctic/Laurasian faunal unit, dominated by microcosmodontids, eucosmodontids, lambdopsalids, adalatheriids, and sudamericids, with relictual flightless kogaionids and ptilodontoideans and perhaps meniscoessids; lime marks the Afro-Arabian faunal unit, dominated by galulatheriids, boffiids, afroptilodontoideans and kogaionids; green marks the Malagasy faunal unit, dominated by kogaionids, afroptilodontoideans, boffiids, sudamericids and adalatheriids; burgundy marks the Caribbean faunal unit, dominated by ferugliotheriids, caribboptilodontoideans, afroptilodontoideans and secondarily terrestrial taeniolabidids; black marks the Oceanian faunal unit dominated by monotremes, dryolestoids, ferugliotheriids, sudamericids, greniodontids and notoptilodontoideans; purple marks the Antarctic faunal unit which is similar but depauperate; yellow marks the South American faunal unit, also similar but with substantial African contributions in the form of afroptilodontoideans, boffiids and galulatheriids.
