#brachiopods — Public Fediverse posts

💁🏻‍♀️ TIL: 🦪🌡️ A #Stanford led study explains why #clams and #snails dominate modern shorelines while #brachiopods barely survived the #GreatDying.

Researchers measured #oxygen consumption in living #animals to show that slower metabolisms could not cope with warming, oxygen depleted waters 252 million years ago. The authors warn that today’s warming #oceans could trigger a similar ecological shift.

This week's Fossil Friday is a Composita brachiopod from the early Carboniferous Banff Formation in Kananaskis! When it was deposited much of western North America was covered by a warm, shallow sea - the perfect environment for marine invertebrates like this to thrive!

The rings on the surface are beekite, which formed when the soft calcite / aragonite of the shell was replaced by more resistant silicate minerals.

436-million-year-old #brachiopods used bristles to avoid crowding neighbors https://phys.org/news/2025-07-prehistoric-social-distancing-million-year.html paper: https://www.pnas.org/doi/10.1073/pnas.2509354122

"Unlike some brachiopods, Nucleospira calypta lacked a stalk and had a smooth, disk-shaped shell—traits that likely let them slide slowly, mm at a time... When 2 individuals got too close, their setae would touch, prompting gradual adjustments over time. The result was a stable arrangement that minimized competition—critical for #FilterFeeders"

The oldest known example in the #fossil record of an #evolutionary arms race.

The 517-million-year-old predator-prey interactions occurred in the ocean covering what is now South Australia between a small, shelled animal distantly related to #brachiopods and an unknown marine #animal capable of piercing its shell.

We’re enjoying finding all the fossils in the limestones we’re using right now to build a garden wall. This one is I believe a brachiopod or ‘lamp shell,’ whose descendants are still around today of course - but maybe someone can correct me if not. I wonder when this one was alive?
They have an arm and a foot, as the Greek parts of their name suggests.
