Lecture 16 Flashcards
Paleoecology when you don’t have clear living counterparts use – to analyze individuals
analogy
IN A STATIC WORLD – may be explained by dispersal from a site of origin
all biogeographic
distributions
IN A DYNAMIC WORLD some biogeographic distributions may be explained by pre-extinction (Noah’s ark) and post-extinction (Viking funeral ship) transport by –
tectonic processes
evidence for Viking ship
long toes and web b/t fingers
Du Toit’s predictive geological map of Antarctica with occurences of the Permian bivlave Eurydesma at – and –
S. America and Africa
Sam Carey drew a large globe to test –
continental drift
bivalve latitudinal gradients showed high diversity at –
equator
find – from families, genera, and species
north pole
Permian bivalve cool and warm clusters –>
break up Asia
Permian paleobiogeography accreted terranes of western north America
suspect –> exotic fusuline forams
paleomagnetic – (to find Pacific islands)
latitudes
biogeographic – (to find Pacific islands)
longitudes
find Hawaii better by using –
larger foraminifera
T/F: break down of Pangea downsized Pacific
true
Belasky list of Permian coral genera, plotted sites, contoured biodiversity, then used low biodiversity to constrain the – of East Klamath
