  1. Oxygen loss in the surface ocean does a number of biology. It's true now, and has been across geological history. Here's another example for that for trilobites during the SPICE event.

  6. Besides taking a photo of the Beardmore sword, my other purpose in visiting the Royal Ontario Museum last Sunday was to see their Cambrian fossils. These are dominated by the OG Burgess Shale fossils (including some collected by Charles Walcott himself) and the newer Mistaken Point lagerstätte in Newfoundland.

    These are three of personal favourite Hallucigenia. Each is a couple of centimeters long (#3 is actually #2 through a low-power microscope, hence the inversion).

  10. "In 2026, a new Cambrian Lagerstätte entered the scene. Paleontologists in southern China uncovered a trove of some of the best-preserved Cambrian fossils to date — a massive collection of 8,681 fossils spanning 153 species — named the Huayuan biota. Many of the Huayuan fossils look similar, if not identical, to those in the Burgess Shale, indicating that these marine ecosystems were connected by global ocean currents.""

    #TheGreatUnconformity — a gap in Earth’s #geologicalrecord. New research suggests it was created by shifting continents, rather than “#SnowballEarth” or #Cambrian life. Evidence that the gap was largely created by #tectonic processes that occurred from 2.1B to 1.6B years ago, in the #Neoproterozoic era, during the formation of an ancient supercontinent called Columbia

  40. El Myllokunmingia fengjiaoa fue un cordado del Cámbrico inferior (518 MdA) de 28 mm de largo. No hay consenso sobre si se trata un vertebrado pero, si lo fuera, sería el más antiguo conocido. Tenía cuatro ojos, conservándose los dos centrales en nuestra glándula pineal. 📷Nix #cambrico #cambrian
