By studying growth rings in fossilized tooth roots, paleontologists have been able to gauge the lifespan and growth rates of these ancient animals, and even when they reached sexual maturity. Researchers were able to image tiny growth rings in fossilized root cement—the bone tissue that attaches the teeth to the jaw. “The rings are similar to those in trees, but on a microscopic level,” explains senior author Professor Thomas Martin of the Vertebrates–Mammals working group at the University of Bonn Institute of Organismic Biology. “Counting the rings and analyzing their thickness and texture enabled us to reconstruct the growth patterns and lifespans of these extinct animals.
