Ancient Scottish Millipede Wasn’t the First Air Breathing Land Animal, Texas Undergrad Proves (and scientists admit they now don’t know what was)

An undergraduate geology student at The University of Texas has helped debunk a long-held scientific theory that an ancient millipede was the first air-breathing land animal.

The research involved dating ancient volcanic sediment near where the millipede fossil was found.

After dating the sediment, the researchers found that the specimen was about 14 million years younger than previously thought, meaning it couldn’t have been the first land-breathing organism.
