Jehol Fossils found in rocks, northeastern China, which often reveal the chalk content of the various species of dinosaurs. When found, the fossil contains dozens of embryos in their bodies. According to researchers, these lizards to death just days before giving birth. Researchers from University College London, who examined the fossil said that the lizard was buried in the Cretaceous period.
This fossil is more interesting because, according to the researchers, they have children, do not lay eggs. According to the study, only 20 percent of the population of lizards and snakes that reproduce by midwives.
Professor Susan Evans, who led the study says, "When I first saw, I do not really care about these fossils." Later, Yuan Wang, associate Susan from the Chinese Academy of Sciences found at least 15 embiro in the fossil. "With the help of a microscope, I can see all the little baby," added Susan. With a closer look, dentition of these embryos could be seen.
Researchers thought that with the birth of reproduction is characteristic of aquatic species. However, these lizards live in the land, although they can swim. "We know that these lizards live near the water and live on land," said Susan. With such a situation, lizards that can dive into water if there are predators who want to eat it.
Fossil lizards belonging to the Yabeinosaurus, namely a large lizard that grows slowly and is quite primitive.
