Researchers have recently discovered an ancient biological fossil called Dendromaia and identified it as the remains of adult and young individuals of the lizard dragon,media reported. The fossil’s history dates back about 300 million years, making it the most famous example of “caring for cubs” among animals on Earth. According to the study of the findings, this pushed forward the evidence of long-term care of the animals for the cubs by about 40 million years.
Researchers at the University of Calton in Canada published their study of these ancient creatures in the journal Nature-Ecology and Evolution. The study shows evidence that adult animals care for their cubs “about 40 million years earlier than previously recorded,” based on analysis of the lizard-dailong during the Guadalan period.” “
Part of the skeleton of the lizard showed its tail surrounding smaller individuals of the same species. This position is most likely to show adult individuals of the lizard dragon huddled in their nests to protect their cubs. In addition, the specimen “adds to the growing evidence that the paleozoic mono-kony animals are more extensive than previously thought to care for their cubs.” “
The two lizards are part of a family of creatures called Varanopid. These things don’t evolve into the lizards we know today, but they exist in the non-mammalian single-hole sub-species.
