Micro-organisms called foraminifera have tiny coiled shells with chambers, not unlike the chambering nautilus but much smaller. In modern oceans the coiling direction of foraminifera shells is correlated to temperature
Using coiling direction from foraminifera fossils is an example of ________.
A) using isotopes to fingerprint temperature
B) using the fossil's coiling direction is a proxy for climate because the surface water temperature would be highly correlated to surface temperature
C) geomagic; the whole idea is preposterous
D) using the fossil as a paleo-depth indicator because water temperature varies with depth
