Lepidosaurs are scaled reptiles such as lizards, snakes, and New Zealand's tuatara, which together represent the most diverse group of land-living vertebrates alive today. Yet little is known about their early origins compared to the other arms of reptilian evolution which produced crocodiles, birds, and turtles... The fossil, found in Ischigualasto Provincial Park in northwest Argentina, is about 11 million years younger than the oldest known lepidosaurs from Europe, but one of the best-preserved specimens of its kind, which means the team can have more confidence in their analyses... It's a lucky find, especially considering the origins of lepidosaurs have been a gaping hole in evolutionary knowledge because of an "extremely patchy early fossil record comprising only a handful of fragmentary fossils", mostly found in Europe and often poorly preserved, the research team explains... In a cross-continental effort, the research team examined the skull's structure using a high-resolution micro-CT scanner and analyzed the images. The Taytalura skull had unique teeth and an unusual combination of features the team was not expecting to find in such an early specimen, preserved in three dimensions of astonishing detail... Some of its features resembled modern tuatara more than living lizards and snakes, which suggests the latter actually represents a major deviation in evolution – not so much the tuatara living on windswept New Zealand islands... What's more, the discovery of Taytalura in Argentina suggests that early lepidosaurs were probably able to migrate much further than previously thought – across thousands of miles on the ancient supercontinent Pangea that later split into the continents we see today: Europe to the north and South America in the opposite hemisphere.

Some have said birds evolved from reptiles.
Perhaps this was one of those missing links between the two species. Dramatic changes in physical structure and end usage were more easily and more quickly done with smaller animals such as this critter here.
They’re saying crocodilians, birds, and turtles were a different branch.
it’s almost as if these completely different animals were created instead of evolved from a common ancestor.

Nemotodes are classed by cutting off their rear ends and smashing them on a slide and looking at the patterns.
I always thought that would be a good way to classify people.
LOL

Or God directed the evolution.
I remember that song. It was a huge hit.
I think he performed it on Hee Haw.
Yes. Not only that, but these tiny cold blooded reptiles are actually president and vp of our country.
Ancestor of all scaled reptiles.
And they did not pull that assumption out their fannies.
#13. Take all the makeup off of Nancy Pelosi and Maxine Waters, and what do you have - the direct living descents of the Lepidosaurs.
Lepidosaurs were not the only animals with scales.
The related word lepros meaning "scaly," "scabby" or "rough" is the source of the English word "leprous" (as in leprosy).
Thanks VR.
Colonel Sanders could have made something tasty out of it.
