Was this creature used to date the strata and other fossils like like the Coelanthe was? How many other fossils are assumed to be 11 million years old because they were found in the same strata as a rat squirrel?

And did anybody ever go back and revisit the justification for dates for stata or fossils that were dated based on the Coelanthe? Does anybody even remember how many dates could be affected?

I think you're woefully mixed up about the coelacanth, Danny.

"I think you're woefully mixed up about the coelacanth, Danny."

Other than my spelling, what do you imagine that I'm mixed up about? The Coelacanth being used as an index fossil? Or the concept of index fossils?
