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

#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.

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.

TIL that the first pre-#cambrian #fossil, Charnia masoni, was originally discovered by a 15 years old girl named Tina Negus, who was discounted by her geography teacher saying precambrian fossils were impossible.
A year later it was rediscovered by a boy named Roger Mason, who also took a stone rubbing of the fossil. This time the discovery was taken seriously, and the species is even named "masoni" to this day after him. -

525-million-year-old #fossil defies textbook explanation for #brain #evolution
https://phys.org/news/2022-11-million-year-old-fossil-defies-textbook-explanation.htmlThe lower #Cambrian #lobopodian #Cardiodictyon resolves the origin of euarthropod #brains https://www.science.org/doi/10.1126/science.abn6264
"Until very recently, the common understanding was 'brains don't fossilize.' So you would not expect to find a fossil with a preserved brain in the first place. And, second, this animal is so small you would not even dare to look at it in hopes of finding a brain."
