Thanks for the article.
 

Sub fossil is a misleading term. All the material studied from the impact are fossils even if they are not mineralized because they are old enough: “late Pliocene to early Pleistocene age of ca. 3–2.4 Ma.” I thought that I was going to read an article about an impact that occurred less than 10k years ago. 
 

A lot of workers suggest to mention the age of the remains (2.4 to 3 million years old) as the best way to side step the confusion surrounding the definition of sub fossil.

 

Here is an interesting comment about sub fossils from Steven McQuinn:
