The Oligocene Pelagornis sandersi had the largest wingspan of any bird, estimated between 20 and 24 feet. It was the largest member of the pseudotooth birds, a highly successful family of sea birds with a 50 million year long fossil record. Art by Gabriel Ugueto

This bizarre creature is a Daeodon, a distant relative of hoofed mammals like pigs. Unlike them, it was a predator, and would hunt large prey like Calicotheres and primitive Rhinos in its home of late Oligocene-early Miocene North America.

Spectember Challenges 2021: Week 1 - Oligocene Oddballs!

The Oligocene was a pivotal time in the Cenozoic, with massive ecological turnover leading to the more familiar faunal composition seen across the world today. In celebration of the bizarre lineages our planet saw at the time, this week’s challenge is dedicated to them.

Prompt: Create a modern day descendent of a lineage that went extinct by the end of the Oligocene, approximately 23 million years ago.

The speculative organism must descend from a described species from the Oligocene. Originality and the inclusion of explanatory text are highly encouraged.

You will then have one week (until September 9th at 9am Pacific Time) to submit your entry for the challenge. In order to enter, you must use the Spectember Challenge flair (please do not use the flair if you are not submitting art for a challenge). Art submitted will also need to be your own original content; reposts will be barred entry.

Voting will commence for the three top-rated entries for this prompt in exactly one week. Please remember at this time that vote manipulation is not allowed, and that karma will not be the only factor in deciding the top entries. As such, you are encouraged to upvote all entries that you believe execute the prompt well. The winning user of this challenge will be crowned "Spectember Champion" and receive a matching flair.

Best of luck to all participating, and happy Spectember!
