300 Million Year Old Brain Recovered
>


An unutterably old brain of a shark's antecedent was found in Kansas

More than just dust in the wind, a 300 million year old brain was unearthed in Kansas. According to scientists, this represents the first time that actual brain tissue of the period was fossilized and can be recovered. Less than 3 years ago, small scraps of T-rex vascular structures were found on fossilized bones, but this discovery is apparently far more complex. The fish-like iniopterygian was a predecessor of sharks, rays, and fish and lived in a shallow ocean in the middle of the continent. (See example below)
