No other paleontological site in the world has as great a potential to answer these questions as the La Brea Tar Pits. Berkeley and the Museo Nacional de Historia Natural in Uruguay.
A beloved holiday tradition returns.’Twas the night before Kitzmas and all through the land, No creationist was stirring, not even Ken Ham; The briefs had been drafted and filed with great care,...read In part 1, I observed that there are two obstacles that might seem to face teachers wanting to use recent extreme weather, like Hurricane Harvey, in teaching about climate change: the complexities...Anna Holden Richard Gilder Graduate School, American Museum of Natural History, New York, NY We are updating the current status and distribution of the extensive insect collection at Rancho la Brea.Most of these insect species are still living today though not necessarily in southern California.Recent studies include insect trace fossils in bone and wood, exquisite preservation of leafcutter bee nests and pupae, identification of previously undescribed plant galls and new methods to extract asphalt from insects for radiocarbon dating. Greg Mc Donald Regional Paleontologist for the Bureau of Land Management, Utah State Office, Salt lake City, UT My research focus at Rancho La Brea is on the giant ground sloths and trying to understand their paleoecology.
I am also interested in the taphonomy of asphalt deposits and how Rancho La Brea compares to other similar deposits which preserve Pleistocene faunas, especially those in South America that also include ground sloths.I have a BS in Biology and Natural Resources from Cornell University and just received my Ph D in Biology from Stanford University, working closely with the Museo Nacional de Historia Natural of the Dominican Republic.At La Brea, I use stable isotopes of Holocene fauna to develop a baseline for understanding the rapidly changing biodiversity of Los Angeles. Campbell Curator of Fossil Birds, Natural History Museum of Los Angeles County My current research on the fossil birds of Rancho La Brea includes two major projects.I work to understand past systems while conducting contemporary research to see how these systems have changed and how they may continue to change in the future.This research depends on historical or ancient information and citizen scientists are playing an increasing role in making such data available.climate change that affects all species individualistically) and observed (e.g., by testing model predictions against actual events in the paleorecord, such as the late Pleistocene megafaunal extinctions).
