Iapetus Ocean
The
Iapetus Ocean
was an
ocean
that existed in the late
Neoproterozoic
and early
Paleozoic
eras
of the
geologic timescale
(between 600 and 400 million years ago). The Iapetus Ocean was situated in the
southern hemisphere
, between the paleocontinents of
Laurentia
,
Baltica
and
Avalonia
. The ocean disappeared with the
Acadian
,
Caledonian
and
Taconic
orogenies
, when these three continents joined to form one big landmass called
Euramerica
. The "southern" Iapetus Ocean has been proposed to have closed with the
Famatinian
and Taconic orogenies, meaning a collision between
Western Gondwana
and Laurentia.
