Los listrosaurios (Lystrosaurus) fueron unos abundantes dicinodontos que vivieron desde el Pérmico tardío pero que realmente triunfaron en el Triásico temprano, cuando este robusto herbívoro se encontró sin apenas depredadores ni competidores. Vivir en madrigueras posiblemente le permitió sobrevivir al aumento del dióxido de carbono en la atmósfera.📷John Sibbick #permico #permian #triasico #triassic

Glossopteris es un género fósil de hojas del Pérmico (298-251 MdA) cuyos árboles probablemente alcanzaban 30 metros de altura, con troncos de 80 cm de diámetro. 70 de sus especies se han encontrado en el subcontinente indio, pero lo importante es su presencia en Sudamérica, África, Madagascar, el subcontinente indio, Australia y la Antártida, demostrando que formaban parte del continente de Gondwana. 📷Bloopityboop #permico #permian #plantas #plants

One of my favourite houseplants is this Sago palm. Except it isn't a palm, but a cycad (Cycas revulata). One of the few common, non-endagered cycads, it is a native of Southern Japan.

The cycads are a fascinating group - with origins going back to the early Permian (possibly even the Carboniferous), they have survived 3 mass extinction events, including the massive late Permian event, as well as the dinosaur-killing Jurassic event, and the event at the end of the Cretaceous.

Now they are truly endangered again - through climate change, but especially because of human greed. Driven to near-extinction because of poaching. With the exception of a few species, like the sago palm, they are all protected and are not destined for the houseplant market.
