A hallucinogenic fungus, perfectly preserved in amber, suggests that the fungus, the grasses it lived on, and grass-eating dinosaurs co-existed for millions of years.
An analysis of a 100 million-year-old grass specimen perfectly preserved in amber says that the grass was topped by a fungus similar to ergot, the fungus that provided LSD. The study by researchers from Oregon State University, the USDA Agricultural Research Service and Germany, was published online this month in the journal Palaeodiversity.
The analysis suggests that the fungus, the grasses it lived on, and animals that ate grass including dinosaurs co-existed for millions of years.
Ergot, a fungus that grow on rye and wheat is a toxin and a hallucinogen. The hallucinogenic drug LSD is derived from it. People who eat ergot-contaminated grains develop powerful muscle spasms and hallucinations.
The fossil was discovered in an amber mine in Myanmar. Amber begins as a tree sap that can flow around small plant and animal forms and permanently preserve them as it fossilizes into a semi-precious stone.
The fossil dates 97-110 million years ago to the early-to-mid Cretaceous, when the land was still dominated by dinosaurs and conifers, but the earliest flowering plants, grasses and small mammals were beginning to evolve. The fossil shows a grass floret tipped by the dark fungus.
George Poinar, Jr. is an internationally recognized expert on the life forms found in amber and a faculty member in the Oregon State University College of Science. Poinar said:
{The study} shows that this parasitic fungus may have been around almost as long as the grasses themselves, as both a toxin and natural hallucinogen.
Theres no doubt in my mind that it would have been eaten by sauropod dinosaurs, although we cant know what exact effect it had on them.
The fungus in this grass specimen, which is now extinct, was named Palaeoclaviceps parasiticus. Its very similar to the fungus Claviceps, commonly known as ergot.
Much later in evolution, grasses would become a powerful life form on Earth, creating vast prairies, nourishing herds of animals, and eventually providing for the domestication of range animals and the cultivation of many food crops. The rise of crop agriculture changed the entire development of the human race, and its now estimated that grasses compose about 20 percent of global vegetation.
Some grasses have natural defense mechanisms, and ergot may be one of them, helping to repel herbivores, the researchers suggest. Its bitter and not a preferred food to livestock, and its still a problem in cereal and grass seed production, as well as pastures and grazing land.
In animal and human history, the fungus has been known to cause delirium, irrational behavior, convulsions, severe pain, gangrenous limbs and death. In cattle it causes a disease called the Paspalum staggers. In the Middle Ages it sometimes killed thousands of people during epidemics when ergot-infected rye bread was more common. Its been used as a medicine to induce abortion or speed labor in pregnant women, and one researcher whose findings have been disputed suggested it may have played a role in the Salem witch trials.
More than 1,000 compounds have been extracted or derived from it, some of them valuable drugs. They also included, in the mid-1900s, the powerful psychedelic compound lysergic acid diethylamide, or LSD, that is still being studied and has been widely used as an illegal recreational drug.
Bottom line: An new analysis published online in February, 2015 in the journal Palaeodiversity of a 100 million-year-old grass specimen perfectly preserved in amber says that the grass was topped by a fungus similar to ergot, the fungus that provided LSD.

(12,712 posts)We are all dinosaurs on one big. collective acid trip! Now it all makes sense.
Well, I am sure we all agree that, no matter how bad this trip is getting, being a dinosaur is really not all that great. You know, lumbering around making odd sounds, feeling too big to be here. It gets rather boring not being able to stand up and grab a cold beer or something. Some of us eat flora all day and some of us are eating us. Boring.
This trip is rather long and detailed. Time for another hit, man.
BTW, which one of us came up with the asteroid/extinction thing? I want to party with him or her. I bet it was a velociraptor. They always are so cunning.
