#brachiopods — Public Fediverse posts

Enjoyed reading about this nice study @Palaeo3 about the relationship between Li/Ca ratios in #brachiopods and #temperature. The #dataset looks very robust and the empirical relationship highly promising for #paleoclimate #reconstructions!

"#MarineAnimalForests are habitats formed by big groups of #invertebrates—creatures such as #sponges, horse #mussels, and #brachiopods, which look a bit like #clams. These remarkable communities are increasingly being recognized as #biodiversity hotspots"

Ancient marine #animal had inventive past despite being represented by few species https://phys.org/news/2024-07-ancient-marine-animal-species.html

Morphological innovation did not drive diversification in #Mesozoic–#Cenozoic brachiopods https://www.nature.com/articles/s41559-024-02491-9

#Brachiopods were evolving in new directions but this did not become an evolutionary success in terms of the numbers of species... The findings shed light on some core principles of the #evolution of modern #biodiversity.

Sandwich-stacked columns give #brachiopod shells their strength and flexibility https://phys.org/news/2023-08-sandwich-stacked-columns-brachiopod-shells-strength.html

#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.

Less than a week before #Christmas , so out #fossil hunting during the only warm day of the week.
Location: #MineralWellsFossilPark #MineralWells ( #PaloPinto county) Texas.
#Pennsylvanian ( #Carboniferous ) reef deposit.

Lots of #crinoids and #brachiopods as usual. Quite a few #sponges and large stick #bryozoa (alas no veil bryozoa this time), and 3 distinct species of #gastropod.
