me sweating it out on a non-marked biology activity about describing and giving examples of what evolution was doing in specific time periods (i got assigned Miocene and Devonian and i couldnt even fit everything in these screenshots lmao)

The Hibbertopterus meadows would bring to mind the image of a seagrass flat interposed with towering mangrove forests. The colossal eurypterids would be grazing peacefully as shoals of shimmering Devonian bony fish dart frantically around them.

Dunkleosteus is from an extinct clade of armored fish in the late Devonian period that was the top predator of its time. Its teeth were just outcroppings of bone in its face, and it killed with the efficiency of a guillotine with a bite force of a staggering 8,000 psi!

This Psammolepis succumbed to a cold winter during the End-Devonian Extinction and washed ashore with glacial ice about 350 MYA. This ice age may have been caused by the significant spread and increase in size of land plants which weathered rocks and reduced C02 in the atmosphere

[ day 11 ]

A cephalaspis scrapes down the seafloor to search for food.

Cephalaspis is an ostracoderm ( mainly called Osteotraci ) fish from the devonian period, it's name means "head shield" hence the name.

Dunkleosteus terelli, an Orca Sized Placoderm that roam devonian sea.

Dunkleosteus doesn't have any teeth. Instead, it's an extended of it's lower and upper jaw that acts like a teeth.
