Gregarious behaviour in #Carboniferous cyclidan #crustaceans https://royalsocietypublishing.org/doi/10.1098/rsbl.2024.0734

"With legs emerging from underneath rounded shells, #cyclidans looked not unlike an underwater beetle. Earliest species were a few mm in size and form #fossils that look like a tiny bunch of grapes. Over millions of years they evolved larger species, and by the #Triassic they were about as wide as a human hand"

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

Some zooms into my "The Salt Lake Severn" painting (2022) of the Severn Estuary during the Middle Triassic, featuring Thecodontosaurus, cycads, and ferns. Commissioned by the Clevedon Pier Trust.

"the #temnospondyls success lay in their generalist feeding ecology, enabling them to feed on a wide variety of prey... the freshwater habitats they preferred provided them with a relatively stable variety of food resources"

Lagerpeton chanarensis fue un pequeño dinosauromorfo basal del Triásico (236-234 MdA) que podría haberse desplazado a saltos. A pesar de su aspecto, parece que está más relacionado con los pterosaurios que con los dinosaurios. Nobu Tamura #triasico #triassic

In 2020 I illustrated LOCKED IN TIME, written by Dr Dean Lomax. Here's my "Casualties of the Drought" painting, which depicts hundreds of Dutuitosaurus crammed into a drying pond.

El Tanystropheus fue un reptil arcosauromorfo semiacuático del Triásico cuyo cuello era responsable de la mayor parte de los 6 metros como máximo que podía medir. Este estaba formado por 13 vértebras cervicales alargadas, con costillas cervicales. Por ello, requería de un aparato respiratorio capaz de tomar aire sin que gran parte se quedara en la traquea.

#Lizards and #snakes are 35 million years older than we thought
Cryptovaranoides microlanius was a tiny #lizard that skittered around what is now southern #England during the late #Triassic, around 205Mya. University of Bristol has analyzed that #fossil and determined that Cryptovaranoides is not an archosaur but a lepidosaur, part of a larger order of #reptiles that includes squamates, the reptile group of modern snakes and lizards. It is now also oldest known squamate.

El Rhynchosaurus articeps fue un reptil arcosauromorfo herbívoro del Triásico medio (247-242 MdA). Tenía pico, con dientes anchos y planos en el maxilar y paladar, que iban sustituyéndose de atrás a adelante, aunque el desgaste por comer raíces y tubérculos hacía que acabaran muriendo de hambre.SeismicShrimp #triasico #triassic

A few words about the recent study of bromalites from Late Triassic to Early Jurassic of Poland, delving into how and why dinosaurs became so succesful.

Pár slov k nedávné studii bromalitů z pozdního triasu a rané jury Polska, která se ponořila do otázek, jak a proč se dinosauři stali tak úspěšnými.

Late #Triassic Cryptovaranoides microlanius is a squamate, not an archosauromorph https://royalsocietypublishing.org/doi/10.1098/rsos.231874

"the #fossil is related to modern #anguimorphs such as anguids and monitors. The discovery shifts the origin of the whole lizard-snake group, called #Squamata, back by 35 million years."

El Arizonasaurus babbitti fue un ctenosauríscido del Triásico medio cuyas apófisis espinosas de sus vértebras se elongaban hasta formar una vela dorsal. #triasico #triassic

El Shringasaurus indicus fue un alokotosaurio del Triásico medio, un herbívoro con dos cuernos sobre la cabeza y 3-4 m de longitud que probablemente vivía en manadas. Los cuernos son más grandes en los considerados machos adultos, por lo que habrían servido en la selección sexual.Mario Lanzas #triasico #triassic

El Hallopus victor es una criatura misteriosa. En un comienzo, se creyó que era una especie del dinosaurio Nanosaurus, pero se cree que fue un pequeño pseudosuquio del Triásico tardío. Petr Menshikov #triasico #triassic
