Insect borings on titanosaur fossils at Lo Hueco reveal longer carcass exposure

Insect borings found on 70-million-year-old titanosaur fossils at Lo Hueco suggest carcasses were exposed longer than previously thought. This discovery challenges the idea of rapid burial, indicating specialized insects like dermestid beetles had time to bore into bones and dermal armor. The findings revise the paleoecological understanding of the Late Cretaceous at Lo Hueco, offering new insights into sedimentary and environmental dynamics.
