The lizard was just days from giving birth when it died and was buried
A 120-million-year-old fossil is the oldest pregnant lizard ever discovered, according to scientists.
The fossil, found in China, is a very complete 30cm (12in) lizard with more than a dozen embryos in its body.
Researchers from University College London, who studied the fossil, say it was just days from giving birth when it died and was buried during the Cretaceous period.
The team reports the findings in the journal Naturwissenschaften.
