Late Devonian //

The early forests of Late Devonian altered the environment, forcing animals to adapt. Creatures like Tiktaalik, a transitional animal showing traits of both fish and amphibians, lived in this period.

Progress made on my series Deep Time Dramas! Working to combine and expression. Plenty more to go on these (including actually adding animals ofc)

2. The Ordovician/Silurian Extinction - indecision, separation

Pterygotus was a gigantic arthropod that could grow to 2.3 metres long! They lived during the early Silurian-Devonian period. They had a pair of large eyes & a smaller pair in the centre of their head.

Fun fact: boreaspis was the most suspicious prehistoric fish & did not work well together. This made them easy prey & actually caused them to go extinct long before the Late Devonian Extinction 🙃
