💁🏻♀️ 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 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 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.

Dinosaur dental #fossils reveal bird-like parental care bonds https://phys.org/news/2026-05-dinosaur-dental-fossils-reveal-bird.html
"Baby #dinosaurs were likely fed more nutritious food than their adult counterparts... Paleontologists uncovered this by studying wear on the fossilized teeth of #Maiasaura peeblesorum, a duck-billed dinosaur that lived during the Late #Cretaceous... The urge for a bird to feed a youngster is a very old behavior... it probably goes much further than the origin of #birds, perhaps to the origin of dinosaurs."

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
