This famed stretch of English coastline is subject to erosion and frequent collapse, resulting in an “ever changing landscape,” according to Dorset Council. “Wind, waves and weather all act on the cliffs which can fall and slip without warning,” tweeted the regional authority, so people should “keep away from the tops or bases of the cliffs and stay off slip material on the beach.”

This shoreline is often referred to as the Jurassic Coast, and for good reason. The area is “well known for its beautifully preserved and scientifically important fossils,” as Sven Sachs, a paleontologist at Naturkunde-Museum Bielefeld in Germany, explained in an email.

Important fossils pulled from the Jurassic Coast include a previously unknown species of ichthyosaur and the discovery of a squid-like creature still clinging to its prey. That stratigraphic layers from the Late Jurassic might now be exposed by the rockfall is wholly possible, said Sachs, and there’s a “chance that interesting fossils can be found.”

In an email, Steve Brusatte, a paleontologist at the University of Edinburgh, said he’s aware of the rockfall but is not yet sure which types of rocks were involved in the collapse. They could be “Jurassic-aged rocks or rocks of other ages or types,” he wrote, as there’s a “diversity of rock ages and types on the Jurassic Coast.”

Brusatte suspects the collapse has exposed some fossils, but he issued a warning, saying people shouldn’t “go rushing to find them yet, the cliff still looks really unstable and dangerous.”

Indeed, the rockfall is still fresh, and more collapses are possible in the coming days and weeks. Should this patch of the Dorset shore eventually be opened up to paleontologists, however, it’ll be exciting to see what they might find. Some stupendously important fossils could now be lying there, just waiting to be discovered.
