Raises a good question, though–how are they dating this specimen? The article doesn’t tell us what places this fossil in the early Triassic.

biostratigraphic process:
“They dated the fossils based on the layer of rock in which it was found and the ages for the layers above and below it (over time layers of sediment accumulate on top of remains, making a vertical slice somewhat of a timeline into the past).

And how do they date the rocks? They use index fossils. What’s an index fossil? I looked it up for you. Here’s a link:
http://www.thefreedictionary.com/index+fossil. So, they date the fossils according to the rocks they find them in, and they date the rocks according to the fossils they find in them. Makes sense, right?
