Dinos Got High, Oldest Grass Fungus Fossil Hints

Millions of years before LSD and rock and roll, dinosaurs munched on psychedelic fungus, a new study suggests. The hints that dinos got high come from the first amber fossil ever found of ergot, a grass parasite that can have poisonous and mind-altering effects on animals that nibble the dark fungi.

Ergot provided the precursor to LSD (lysergic acid diethylamide). And people who eat ergot-contaminated rye (or other ergot-tainted grains) develop powerful muscle spasms and hallucinations. The phrase "St. Anthony's Fire" refers to both ergotism and the horrible burning feeling that ergot triggers by constricting blood vessels.

Now, it turns out that ergot has plagued grass-eaters since dinosaurs stomped the Earth. The hunk of amber from Myanmar encases an exquisitely preserved ergot fungus, perched atop a grass spikelet that grew about 100 million years ago, researchers report in the 2015 issue of the journal Palaeodiversity. The amber was excavated in a mine and collected by Joerg Wunderlich, a German paleontologist.
