  1. A Billion Years Are Mysteriously Missing From #Earth’s History. Now, We Know Why.
    #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

  11. #Chitonida (#Mollusca) exist since the #Cambrian. Bodies are covered with #calcareous #plates, flexibly connected. Most feed on vegetation cover. The #CambrianExplosion made based i.a. on #oxygen significant leaps in #animalevolution. Y. Zhang et al. (2025) assume a change in Earth's orbit altering #solarradiation, leading to land #weathering and #nutrients flow to the sea. Algae thrived and produced much oxygen.

    A new #Cambrian stem-group echinoderm reveals the #evolution of the anteroposterior axis: Stephanie Woodgate et al. cell.com/current-biology/fullt

    "The fossil, #Atlascystis acantha, is the oldest known #echinoderm with a bilateral body plan. It bridges the evolutionary gap between the closest living relatives of #echinoderms, all of which have bilateral symmetry, and the familiar five-armed forms alive today."

  18. Thinking about fossil marine invertebrates that Kielan-Jaworowska studied at the beginning of her career, made me think of this pattern made from my linocut animal prints with collaged washi papers from the Cambrian Period (from 538.8 million to 485.4 million years ago). 🧵

  19. For a wildcard #InsertAnInvert2024 week we’re going back in time all the way to the Cambrian for the Opabinia! The fossils of this soft-bodied 7 cm long animal are found in the Middle Cambrian Burgess Shale Lagerstätte (505 million years ago) of British Columbia. Opabinia likely caught prey with the grasping claws on the end of its long tubular proboscis (like an elephant’s trunk). 🧵1/2

  21. My art in 2023 (6/12)

    June: Anomalocaris, Dragon of the Cambrian. The realisation that most Cambrian creatures were tiny gave me the idea of a whole bunch of them hiding from a 40 cm long Anomalocaris while in positions reminiscent of a D&D party facing off against a dragon.

  23. Presenting: THE #CAMBRIANSMACKDOWN! A silly Tumblr style bracket. I will create a series of polls to determine which screwy looking Cambrian era critter is perceived as the coolest on Mastodon!
    Polls will start at 7 days long.
    Depending on how well-received this is, the polls may shorten in length.
    Polls coming soon. Enjoy. This thread will be for bracket updates rather than the polls.

  24. Mighty #Anomalocaris stirs, spreading dust and terror throughout the #Cambrian sea. #Opabinia, #Hallucigenia, #Pikaia, #Canadia, #Burgessia, #Marella, and #Elrathia can only hope the rocks and ridges they cover behind will hide them.

    Inspired by a display at the Naturkunde Museum Stuttgart that perfectly showed off the difference in size between Cambrian critters. At 40 cm, Anomalocaris was a leviathan.
