Tametara mirim es una serpiente excavadora del Cretácico tardío (85-75 MdA). Apoyaría la hipótesis de que las serpientes perdieron sus miembros para facilitar el movimiento subterráneo, en lugar del acuático o sobre la hojarasca, como también se planteaba. 📷Gabriel Ugueto #cretacico #cretaceous

💁🏻♀️ TIL: 🌍🧭 Researchers at the University of #Barcelona built a free web tool that converts current #fossil coordinates to where those locations sat millions of years ago.
It runs five global plate tectonic models simultaneously and shows automated results nearly identical to desktop #software, with an average spatial error under 17 meters.

💁🏻♀️ TIL: 🦴🐟 A #fossil from #Australia’s #Cretaceous #Eromanga Sea captured a rare three-tier predator interaction: a #pterosaur eaten by an #ichthyosaur, then both consumed by a giant #pliosaur called '#Kronosaurus queenslandicus.'
Researchers used #neutron #tomography to identify pterosaur jawbones in the ichthyosaur’s fossilized stomach alongside crushing bite marks from the larger #predator.

An article published in the journal "Gondwana Research" reports the discovery of an ichthyosaur fossil in present-day Australia that preserved the contents of its stomach, which includes the remains of a pterosaur. The ichthyosaur itself shows remarkable signs of having been bitten by a pliosaur, which literally broke its bones.

💁🏻♀️ TIL: ☄️🔥 A recent study from #Purdue suggests fine dust from the #Chicxulub impact trapped heat in the upper #atmosphere, effectively charbroiling exposed organisms within hours.
Post-impact dust would have delivered 17 times the lethal #radiation dose for #humans, igniting #grass and #lichen across the #planet.

💁🏻♀️ TIL: 🦖💰 A T. rex #skeleton named Gus, found in #SouthDakota in 2021, is heading to auction at #Sotheby’s with an estimated price of $20 to $30 million.
The 11.5 meter specimen is one of the largest and most complete T. rex skeletons ever found. Paleontologist Scott Persons argues that sums like this could instead fund a career’s worth of #fieldwork and public exhibition at a #museum.

The “Chicken Yard” track site, lower Cretaceous of Germany, in an older oil painting. This piece won’t be in the upcoming PALAEONAVIX SHOP, but awaiting a new home with some friends of ours.

The dinosaurs 🦖 could smell flowers 🌺, so did early mammals. Both because some of them had a good sense of smell and also because flowers became a thing that exists on Earth during the Cretaceous.

Turning this Triceratops head to greyscale became similar to an old Pachyrhinosaurus sketch from more than 20 years ago.Like some coat of arms or antique shield.

Arthurdactylus conandoyle es un pterosaurio del Cretácico temprano (115-113 MdA) relativamente pequeño, con 4,5 m de envergadura y 15 kg de peso. Debe su nombre al autor de El mundo perdido (1912), donde el profesor encuentra un gran pterosaurio sobre una meseta en Sudamérica. 📷Joschua Knüppe #cretacico #cretaceous

💁🏻♀️ TIL: 🦖👃 T. rex breath likely smelled like rotting meat, thanks to bits of prey getting stuck between its widely spaced #teeth.
To create an exhibit at #Chicago’s #FieldMuseum, developer Ben Miller used a synthetic corpse smell originally designed for training disaster response #dogs.

💁🏻♀️ TIL: 🦖🌍 What if the #asteroid missed?
What would #Earth be like if #dinosaurs survived? #Mammals would remain small, #Trex could have lost its arms entirely, and #troodontids like the Stenonychosaurus might have evolved human-like #intelligence, with #humans never appearing.

El Tylosaurus rex fue un mosasaurio de 7,6-13,1 m de longitud del Cretácico tardío (80 MdA) con dientes serrados. Anteriormente, los especímenes estudiados se incluían en T. proriger. 📷Alderon Games (Path of Titans) #cretacico #cretaceous

💁🏻♀️ TIL: A 12-meter tall T. rex named Gus goes up for #auction July 14 after a six-year excavation and lab prep process that started on a #SouthDakota cattle ranch. 🦴
There's an ongoing #debate about whether big #fossils belong in #museums or private collections. 💰

Giant, #kraken-like #octopuses may have ruled the #Cretaceous deep
Fossilized jaws reveal that enormous octopuses growing up to 19 meters long were top predators in the #oceans during an era when #dinosaurs ruled on land. These super-sized #cephalopods would have been the largest marine animals of the Cretaceous Period and may be the biggest #invertebrates to ever live

🦖☄️ Paleontologist Michael Benton and meteoriticist Monica Grady reconstruct the final day of the #Cretaceous in real-time – from the silent #asteroid visible as a #star, to the fireball and incineration, to mega-tsunamis, global #wildfires, acid #rain, and a decade-long #winter that snuffed out three-quarters of #Earth’s species.

🦖☄️ 66 million years ago, an #asteroid wiped out 75% of #Earth’s species. The survivors – small #birds, #mammals, #turtles, and #fish – shared key traits: a small body size, the ability to burrow or shelter in #water, and flexible diets. Researchers explain how size, diet, and luck determined who lived and who didn’t.

🦴🔬 A #fossil sitting in a #museum drawer since 1979 turned out to be a brand new species: *#Tylosaurus rex*.
Lead researcher Amelia Zietlow (#AMNH) noticed that a #Texas #mosasaur specimen labeled as a known species didn’t match its relatives. The 13-meter-long apex #predator had serrated #teeth, massive jaw #muscles, and battle #scars from fights with its own kind.

Oculudentavis fue un género de lagartos diminutos encontrados en ámbar de Vietnam de comienzos del Cretácico tardío (99,41-98,17 MdA). Cuando se encontró la cabeza del O. khaungraae, se indicó que era un ave, habiendo sido la más pequeña de haber sido cierto, pero el análisis anatómico y el descubrimiento del O. naga permitieron desechar esa idea. 📷Lida Xing #cretacico #cretaceous

The #Cretaceous hothouse had atmospheric #CO₂ levels above 1,000 ppm, compared with 420 today, and temperatures up to 10℃ higher than today. It was caused by very fast-moving #tectonic plates, which increased CO₂ emissions. Tectonic plates slow down due to collisions, which leads to mountain building. The weathering of igneous rocks is very efficient in reducing atmospheric CO₂. Spreading olivine on beaches could absorb up to a trillion tonnes of CO₂ from the atmosphere https://www.sydney.edu.au/news-opinion/news/2022/05/26/how-plate-tectonics-have-maintained-earth-s--goldilocks--climate.html
