Fossilized Burrows 245 Million Years Old Suggest Lizard-like Creatures In Antarctica
            


Scientists find evidence of tetrapods living in Antarctica during the early Triassic epoch, about 245 million years ago. The fossils were created when fine sand from an overflowing river poured into the animals' burrows and hardened into casts of the open spaces. The largest preserved piece is about 14 inches long, 6 inches wide and 3 inches deep. The burrows' relatively small size prompted scientists to speculate that their owners might have been small lizardlike reptiles called Procolophonids or an early mammal relative called Thrinaxodon.

There are areas where the ground is exposed but its arid and cold so all the bacteria have died.

I saw a show where they augered thru the icecap several thousand feet down.
At the bottom they hit dirt/mud.

The samples were to be analyzed for bacteria and nutrients.

Yep at one time it was probably plush with life.

245M years ago it was farther North and the temps were way warmer.

I thought it was cool enough that that dirt was untouched for millions of years and those scientists were the first to see it.

Never saw the follow up for the soil results.
I missed my chance to work there about 15 years ago on a NSF project.
