Dino-Era Lizard Is Missing Link to Swimming Reptiles, Experts Say
A lizard whose fossilized bones were discovered near Dallas, Texas, 16 years ago is a missing link in the evolution of extinct swimming reptiles known as mosasaurs, a new study says. The ancient lizard, named Dallasaurus turneri, measured three feet (about a meter) long and lived 92 million years ago in shallow seas that covered what is now Texas.
