Paleontologist Matt Friedman was surprised to discover a remarkably detailed 319-million-year-old fish brain fossil while testing out micro-CT scans for a broader project.
therefore have implications for interpretations of neural morphology during the early evolutionary stages of a major vertebrate lineage."Some brain features would have been lost to decay and the preservation process, but the team could still make out specific morphological details. This allowed them to see that the way this prehistoric forebrain developed was more like ours than the rest of the living ray-finned fishes alive today.Friedman.
The researchers are keen to scan other fish fossils in the museum's collections to see what other signs of soft tissue may be hiding within. "An important conclusion is that these kinds of soft parts can be preserved, and they may be preserved in fossils that we've had for a long time – this is a fossil that's been known for over 100 years,""That's why holding onto the physical specimens is so important. Because who knows, in 100 years, what people might be able to do with the fossils in our collections now.
