Extract from Murchison's journal: 'Oct 4th 1825 Accompanied by Mary Anning rode to Dowlands and dismounted there. First examined the real inland cliff above the undercliff.'

200 years ago today, 4 October 1825: visiting Lyme Regis, geologist Roderick Murchison notes in his journal: 'Accompanied by Mary Anning rode to Dowlands and dismounted there' where they examined the Greensand rocks of the Undercliff, the landslipped coastal cliffs west of the town.

Congratulations, #Kyanite!

After eight years of competing, another few hours to verify votes was nothing, right?

Amazing first run, #Tugtupite, and better luck next year.

Woolley and colleagues examine in detail the relationship between inferred environments in which a fossil squamate species was buried and the completeness of its remains. Environmental and geological processes play a strong role in how complete the fossil record can be. You’ll notice that mosasaurs are almost exclusively found in marine settings and are more complete on average than other groups. Snakes, on the other hand, are found nearly everywhere, but are highly incomplete. Chart courtesy of Hank Woolley.

From the Press Room | For the more than 242 million years that lizards and snakes appear in the fossil record, they show up as mostly pieces of lizard jaws and snake vertebrae. Exactly why these parts survive as fossils has been a mystery—until now: go.nhm.org/megafilters

Did someone order seafood on the menu? Here are the shells of the oyster Exogyra cancellata. These come from the Late Cretaceous (Late Campanian) Demopolis Formation in Tueplo, Mississippi. These oysters are so common that you fill your backseat with them.

September 18, 1972, Kenneth Jinghwa Hsu, Maria Bianca Cita & William B. F. Ryan publish the results of the 1970 Glomar Challenger expedition and drilling operations, suggesting the Mediterranean Sea dried out during the Messinian age (7.2 - 5.3 million years ago).
