#brachiopod — Public Fediverse posts

@jmccyoung Fascinating! with a terrific chart of the drama 250m years ago: "the bivalves could adapt better to high ocean temperatures. So, this gave them the edge, and after the Jurassic, they just rocketed in numbers, and the brachiopods didn’t do much.”

Small fossilized Brachiopod shells. The remains of these shellfish are scattered throughout the limestone rocks of the Burren.
County Clare, Ireland.

A Brachiopod fossil with some Small Periwinkles (Melarhaphe neritoides) on and around it. A Marine shellfish of the past and some from the present day, whose lives are separated by over 300 million years.
County Clare, Ireland.

Brachiopod fossils, in shale. Certain shale layers in the Cliffs of Moher and some of the limestone layers in the Burren are packed with the fossilized remains of these ancient shellfish.
County Clare, Ireland.

I think this may be a pair of fossilized Brachiopod shells 🤔

This sandwich-like structure of columns gives strength and flexibility to the shell of a #brachiopod and has helped researchers understand the evolution of these distinctive structures during the Cambrian explosion. #Evolution #ReviewedPreprint #12DaysOfeLife https://elifesciences.org/reviewed-preprints/88855?utm_source=mastodon&utm_medium=social&utm_campaign=organic_12Days

#Brachiopods have hard shells on their upper and lower surfaces. This gives them the appearance of a clam, although they are unrelated. #LinguliformBrachiopods are of particular interest due to their lightweight, strong, and tough shells.

Happy #fossilfriday . This is a pyrite fossil of a 400 million year old brachiopod from Ohio.

Purchased by my father at an art festival ~40 years ago, it hung in my office for 15 years until the pandemic. Every afternoon it would catch the sun.

Parasite-induced shell damage in brachiopod Porambonites (Porambonites) laticaudata from the Late #Ordovician (Sandbian) of #Estonia

https://doi.org/10.3176/earth.2023.23

The pits in the shell margin are most likely caused by the presence of symbionts which benefitted from inhalant currents and caused damage to the host #brachiopod. This is consistent with #parasitism rather than previously know damage linked with failed attacks by durophagous #predators.
