  1. 🦖☄️ 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.

  2. 🦖☄️ 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.

  3. 🦴🔬 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.

  8. Antarctica, 108 million years ago. A group of Leaelynnasaura is fascinated by the bright spot that appeared on the Moon's night side as a large meteorite struck it, forming the Tycho crater.

    This piece was inspired by the Artemis II mission.I wanted to paint something about the Moon, and was delighted to discover the prominent Tycho crater on the Moon's surface formed right in the middle of the Cretaceous period!

  9. 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 sydney.edu.au/news-opinion/new

  14. El Nanaimoteuthis haggarti fue un pulpo cirrino del Cretácico tardío (100-72 MdA), conocido por su pico, cuyo tamaño se estima entre los 6,6 hasta los 18,6 metros de longitud. 📷Yohei Utsuki #cretacico #cretaceous

  15. El Gigantoraptor erlianensis del Cretácico tardío (95-80 MdA) es el mayor oviraptosaurio conocido, con 8-8,6 metros de longitud, que ocasionalmente pudo haber comido carne, desgarrándola con su pico. Dado su tamaño, pudo carecer parcialmente de plumas para la temorregulación. 📷ABelov2014 #cretacico #cretaceous

  21. Scypionyx samniticus fue el primer dinosaurio italiano conocido, una pequeña cría de 46,1 cm de longitud del Cretácico temprano (113 MdA) cuyo fósil conserva la huella de muchos tejidos blandos, especialmente los internos. 🏛️Museo de las Ciencias de Trento 📷Matteo De Stefano #Cretacico #Cretaceous
