>That may have proved a problem for ammonites, which routinely fed on their own offspring.

How can we possibly know that about species extinct for over 60 million years??

Edit: nice down vote without a comment, stay classy

Probably because many fossils have been found showing partially digested juvenile ammonites inside adults, I expect. That’s how they found out placoderms (which went extinct 360 million ya) gave birth to live offspring.
