And, I started daydreaming about encountering something a little different, maybe a Horned Frog, Ceratophrys cornuta, a large, squat green and brown frog of South America, with a wide mouth large enough to eat other frogs as well as reptiles. If you don’t live near a science museum, then read this chapter. This is not a field guide.
Manker’s thesis is that ornithology is an excellent gateway to students becoming science majors in college and, more broadly and longer-term, conservation-minded citizens. That article left an impression and I have wondered what became of Manker’s effort to create a high school ornithology curriculum. Think about it for a minute.
To elucidate underlying developmental mechanisms, we examined candidate gene expression domains in the embryonic face: the earlier frontonasal ectodermal zone (FEZ) and the later midfacial Wnt-responsive region, in birds and several reptiles. Well, maybe a little better than that but not much. Caption for image at top of post: Figure 2.
We nature bloggers were part of the scene, first as part of the seminal science carnival Tangled Bank and later with our own community carnivals like, of course, I and the Bird. Remember the blog carnival craze? We deserve our own toplist, don’t we? That’s right…. Presenting the Nature Blog Network, the toplist for the nature blog community.
As I frequently mention, science is quite wonderful. It still is a cool bird looking a bit like a reptile. If you are tired of watching action movies, take a look at one minute of non-action by a female Red-flanked Bluetail. but also my personal statement regarding your reaction to seeing yet another photo of White’s Thrush.
So, I welcomed the opportunity to read and review Flying Dinosaurs: How Fearsome Reptiles Became Birds , by John Pickrell, published in the United States by Columbia University Press. There is a lot of science here to explain. Flying Dinosaurs: How Fearsome Reptiles Became Birds is an example of good, solid scientific writing.
The reptile was battered with repeated lunges and stretched between talon and beak, but continued to wriggle until the young hawk managed to get a good grip on the head and after that there was only likely to be one outcome. It was clear that it had nearly caught something, but the prey was not giving up without a fight.
Turtles are the reptile everybody loves. It’s useful to remember the names of the two suborders of Testudines (the reptile order that includes all turtles): Cryptodira (turtles that retract their heads vertically and sea turtles–most of the turtles in the world) and Pleurodirans (turtles that retract their heads sideways).
After one 3 year stint, they left with 131,405 specimens including birds, mammals, reptiles, plants and even human remains (which were only recently repatriated for burial in Africa!) The famous Verreaux family who made several expeditions into the province through the 1820’s and 1830’s procuring specimens for rich collectors.
But it is utterly bewildering to me to see news reports about this recent science that read “… An icon knocked from its perch&# or “Archaeopteryx no longer first bird.&# This has happened before, Archaeopteryx and the bird family tree have had an often tenuous relationship.
