...around 66 million years ago, they mysteriously disappeared from the fossil record. The end-Cretaceous extinction, sparked by the impact from a massive asteroid, wiped out approximately 75% of all life on Earth, including all of the non-avian (bird-like) dinosaurs. Thus, it was presumed that the coelacanth fishes had been swept up as a casualty of the same mass extinction event. But in 1938...
...a mass extinction event wasn't even considered, and wouldn't be until after the Chicxulub impact crater was discovered (1951, 1978) and identified (1991) as the source of the iridium layer in the thin layer that caps the Cretaceous.
A newly discovered ancient coelacanth from Western Australia provides critical insights into evolutionary biology, highlighting the influence of tectonic activities on the emergence of new species and tracing the lineage that connects ancient fishes to humans.
