Aptij

Aptij je doba u geološkoj vremenskoj skali ili stadij u stratigrafskom stupcu. To je dio rane ili donje krede, epohe ili stratigrafske serije, sa vremenskim rasponom od prije 125,0 ± 1,0 do 113,0 ± 1,0 miliona godina (približno). Atij je došao iza baremija, a prethodio je albiju, dijelovima donje/rane krede . Aptij se djelimično preklapa sa zapadoevropskim stadijem zvanim urgonij

Događaj Selli, poznat i kao OAE1a, bio je jedan od dva okeanska anoksijska događaja u razdoblju kreda (period) krede, koji su se dogodili prije oko 120 miliona godina i trajali otprilike 1 do 1,3 miliona godina.^[1]^[2] Aptijsko izumiranje bilo je malih razmjera, a pretpostavlja se da se zbilo prije oko 116 do 117 miliona godina.^[3]
