Amber fossil links earliest grasses, dinosaurs and fungus used to produce LSD.
"The present discovery establishes: 1) the first fossil record of a progenitor of Claviceps. 2), a minimum date for the establishment of plant parasitism in the Clavicipitaceae. 3), supportive evidence for the earliest known fossil Poaceae in the Early–mid Cretaceous, and 4), a minimum time for the conceivable presence of psychotropic compounds. This fossil also provides new insights into the origin and evolution of plant parasitism by the Clavicipitaceae"
