4/ As climate change drives modern forams poleward and reduces tropical diversity, Fraass warns: these ancient records aren’t just history they’re early warnings. "Geology gives us glimpses of futures we should try to avoid." @uvicscience.bsky.social

3/ Fraass and colleagues found that modern plankton communities emerged ~15 Mya after cooling stabilized. Fossil records show that ecological changes often happen before mass extinctions key knowledge for interpreting today’s ocean disruptions

2/ The K/Pg extinction (~66 Mya) wiped out ~90% of planktonic forams. It took 10 million years for their diversity to recover. Later events like the Paleocene-Eocene Thermal Maximum and global cooling at 34 Mya also reshaped ocean life in major ways
