100 million years before the 1960s, sauropod dinosaurs were probably eating a species of psychedelic black fungus that was a precursor to LSD. We know, at least, that the psychedelic ergot coexisted with dinosaurs in present-day Myanmar: Scientists found a fossil of this fungus in amber (leading many* to imagine a weird new version of Jurassic Park crossed with Alice in Wonderland, where scientists clone this hallucinogenic fungus and dinosaurs at the same time.)
Would dinosaurs experience the same sorts of reactions that humans do to psychedelic drugs? It is difficult to say. But it is possible that the K-T extinction wiped out not only an entire range of fauna, but also their creative, LSD-fueled art projects and musical ventures.
Sue in the Sky With Diamonds, anyone?

Millions of years before the psychedelic '60s, dinosaurs may have been tripping on a mind-altering substance that was a precursor to LSD. An amber fossil of ergot, a black fungus, estimated to be 100 million years old was found in Myanmar and provides a link between the fungus, the grass it lived in and the time dinosaurs roamed the Earth.
