Scientists discover clues into lizard evolution frozen in ancient amber.
By Eva Botkin-Kowacki, Christian Science Monitor Staff writer March 5, 2016

<<Some 99 million years ago, 12 unsuspecting lizards stepped or fell into sticky tree resin and couldn't tear themselves loose in the forests of what is now Myanmar. Over time that resin fossilized into amber, preserving the little lizards for scientists to study later. There was a diverse population of lizards living in the region at the time, the scientists report in a new paper published Friday in the journal Science Advances.

"The assemblage is cool because it has some examples which are really, really modern and then others which are really, really old, and then others in between," study co-author Edward Stanley, a herpetology researcher at the Florida Museum of Natural History, tells The Christian Science Monitor. "In the amber we have things that are clearly gecko," says Dr. Stanley. The gecko-like prehistoric specimens have toe pads. Modern geckos use their toe pads to scale walls and perform other sticky-footed feats, but these prehistoric toe pads appear somewhat different. Other amber-preserved lizard specimens had been found with toe pads more similar to those on living geckos, which suggests that "even 100 million years ago geckos apparently already had evolved a well-diversified subset of tools for clinging onto surfaces," Stanley says.

Another block of amber could show "some kind of animal that was on the road to becoming a chameleon," Stanley says. And that specimen, at less than half an inch long, had probably just hatched before it met its demise. A CT scan of the itty-bitty specimen revealed a skeleton similar to those of modern chameleons but also with features more like other lizards. "It's this interesting sort of halfway stop between a modern chameleon and the sister group to chameleons, which are the dragon lizards," Stanley says. This specimen doesn't have the fused digits that today's chameleons have to help them live in trees. But, like a chameleon, it has a shorter spine with fewer vertebrae than its cousin lizards. It also has a characteristically long hyoid bone, the long bone in chameleon's throats that they use to shoot their sticky tongues out at top speeds to capture unsuspecting prey.>>

While gazing at the Milky Way in Cygnus Friday night our backyard was visited by some owlish aliens.

Hey there folks, it's been a while. I thought I'd jump back in by sharing something I saw a last weekend while on a trip to the Oregon Coast (this seems like an appropriate thread). We walked down to see the "cobble stone" beach at Yaquina Head. There were seals poking their heads out of the water just off the shore. Then someone near by enthusiastically indicated the presence of whales. I assumed she meant greys off in the distance; they're common enough in the fall and spring. But then she raised her voice a bit and said, "no, look, just outside the rocks. They've trapped the seals!" It still didn't quite sink in. Then I saw the dorsal fin and realized it was a group of orcas that had pinned the seals between a row of rocks and the shore.

I've visited the coast countless times since I was a kid but I've never experienced anything quite like this. The orcas patrolled back and forth, the seals stayed put - it was a stalemate. I imagine the orcas decided the water was too shallow near the shore or the entrance between the rocks too confining. Either way, they never entered.

The little juncos might like to call this fellow something other than a flicker.
