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: External mold /cast of the cone of Metasequoia: Unidentified leaf cf. Marmarthia
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
Shakum, J. D., 2018. 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.
