Hey, I'm writing a paper on elephant evolution and am a bit murky on the Paleocene-Eocene specimens. I've read that after the PT-thermal maximum, Eocene mammals became the dwarfed counterparts of their Paleocene counterparts. But it seems to me like there's a trend of size increase, not decrease for the Proboscidea ancestors. Am I missing something? Thanks!

Went fossil hunting near Chuckanut BC Canada. These species are I believe Sassafras, Alder, Sabalites Campbelli And for the fern someone said Cyathea But I feel its Neuropteris Flexuosa -
