Preserved fossil represents oldest record of parental care in group of prehistoric reptiles

A fossil specimen discovered by a farmer in China represents the oldest record of post-natal parental care, dating back to the Middle Jurassic.

The tendency for adults to care for their offspring beyond birth is a key feature of the reproductive biology of living archosaurs – birds and crocodilians – with the latter protecting their young from potential predators and birds, not only providing protection but also provision of food.
