The other day I mentioned an interesting study on dinosaur embryos, a day or so later a study on incubation strategies in Troodon was published in Paleobiology. I don’t have access to this article so I will have to rely on the the abstract and the press release on Science Daily. Continue reading
I’m currently working my way through the Australopithecus sediba articles mentioned in the previous post. In the meantime, in wandering around the internet there are a number of things make a science story jump out and say “write about me!” First, if it uses a methodology that answers the question “how do we know?” Second, if it is about life history. Third, if it combines the first two with dinosaurs.
Science Daily (World’s Oldest Dinosaur Embryo Bonebed Yields Organic Remains) points us to a research paper that has all three (plus more). The paper, Embryology of Early Jurassic dinosaur from China with evidence of preserved organic remains, was published in Nature. I don’t have access to the Nature paper so I will have to rely on the Science Daily press release. Continue reading
Phys.Org mentions an interesting article published in the International Journal of Osteoarchaeology. The article concerns a fragment of a whale rib, dating to the Pliocene, that shows evidence of a shark bite. In this case the rib also displays evidence of having survived the attack. From Phys.Org: Continue reading
The Four Stone Hearth will be up later this evening. In the meantime, check out this interesting paper on marsupial carnivores. The paper uses geometric morphometrics to look at skull shape in a wide variety of marsupial and placental carnivores.
The title of this post are two common remarks one hears when the press covers evolution. Drives me straight up the wall. A study published in the Proceedings of the Royal Society B looks at these claims from the standpoint of paleontology and paleoanthropology.
