I found this piece while looking through a kilo of Amber and it's a bit different to the usual - there is something distinctly fibrous inside. Usually its the internal patterns of the Amber but this isn't. Unfortunately, its super hard to photograph. I think its probably something like mold or pollen, although I can't see any distinct seed pods etc - going to clean it up a little more tomorrow. I'd appreciate any input. Thanks, John

Could this be a spore? Found with other pyritized microfossils. Thanks for any help.

Reference Literature for Pollen/Spore/Palynomorph Identification
REW01 posted a topic in Fossil Literature
I have some pollen grains, spores(?), and other non-pollen palynomorphs as well, which I would like to identify that I photographed from a number of slides. However, I have no eye for these things yet (if only my university offered palynology courses!) so I am in need of references to start reading and hopefully use to identify some stuff now and in the future. I know that it's a pretty specialized area, but any input could be helpful as references accessible to people who don't yet know how to identify these things seem to be few and far between. I have access to Paleopalynology b -
I was going through some of my photo files today and ran across some photos of palynomorphs that I extracted from clay underlying a T. rex skeleton in the Hell Creek of South Dakota several years ago. I recovered many plant macrofossils as well. My favorite palynomorph recovered is this Wodehousia spinata, characteristic of Late-Cretaceous and early Paleogene time (sorry the photos aren't the best): Here's a trilete pteridophyte spore: Here are some of the plant macrofossils. Metasequoia: Exter

Hi Its Jimmy Can anyone tell me is it possible for red pollen and green leaves to be preserved in amber? Here are the pics I took today. Any comments are much appreciated. I guess I am wondering if it still has color perhaps it still could have DNA? Jimmy

Pollen weighs in on a climate conundrum Science News and Views, Paleoclimate, January 31, 2018 https://www.nature.com/articles/d41586-018-00943-4 "Simulations by climate models show that Earth warmed during the Holocene epoch, whereas ocean sedimentary cores suggest that global cooling occurred. An analysis of fossil pollen samples now sides with the models." Jeremiah Marsicek, Bryan N. Shuman, Patrick J. Bartlein, Sarah L.
