Anna Holden who recently wrote a guest post here on insects from the La Brea Tar Pits as paleoenvironmental indicators has a lot more stunning insect fossils that have turned up during her studies. She is looking for help to identify more of the specimens. You can check out images of some of the material and if you have expertise in a group offer some suggestions as to the identification. Visit the Flickr account that she has created of ~44,000k year old insects from a unique assemblage. Comment there or for non-Flickr members you can email Anna comments aholden[at]amnh.org.
These insect fossil fragments are in near pristine preservation due to a rapid entrapment event that compacted this material into a camel (Camelops hesternus) skull.
