Atlantogenata (Atlantogenata — „atlansko porijeklo”) ili južni placentalni sisari, je magnred placentalnih sisara.^[2] Ovaj magnred sisara obuhvata nadred Afrotheria i kladus Americatheria.^[6]^[7]^[8] Stručni naziv za članove ovog magnreda sisara je atlantogenati.

Etimologija naziva

Magnred:	Porijeklo naziva od:	Značenje naziva:
Atlantogenata	Atlantskog okeana i starogrčke riječi genos (стгрч. γένος), koja znači porijeklo ili rod	atlansko porijeklo^[2]

Opis

Zajednička osobina koja povezuje sisare iz magnreda Atlantogenata je, pored njihovog genetskog srodstva,^[9]^[10] da mužjaci ne posjeduju mošnice kao drugi placentalni sisara i viviparni sisari, već se njihovi testisi nalaze u unutrašnjosti stomaka.^[11]^[12] Ova osobina je posljedica gubitka gena koji kod drugi sisara omogućavaju da se testisi spuste iz stomaka u mošnice.^[12]

Evolucija

Predstavnici magnreda Atlantogenata vode porijeklo od predaka iz infrareda Placentalia, koji su u periodu kasne krede živjeli na prostoru današnje Južne Amerike i Afrike, dok su ova dva kontinenta još bila spojena i činila kopnenu masu zapadne Gondvane.^[7] Ovi preci su po svom izgledu nalikovali na surlaste rovčice, i bili su mali bubojedi po ishrani. Oko 91,71 miliona godina preci nadreda Afrotheria i kladusa Americatheria su se odvojili u dvije posebne linije sisara.^[1] Ovo razdvajanje se poklapa sa vremenskim periodom nastanka južnog djela Atlanskog okeana, kada su se Afrika i Južna Amerika u potpunosti razdvojile i kada je nestao brazilski kopneni most koji je vezivao ove dvije kopnene mase^[13]^[7]
