The Ordovician Period

Description
Source : Wikipedia
During the Ordovician, the southern continents were assembled into Gondwana, which reached from north of the equator to the South Pole. The Panthalassic Ocean, centered in the northern hemisphere, covered over half the globe. At the start of the period, the continents of Laurentia (in present-day North America), Siberia, and Baltica (present-day northern Europe) were separated from Gondwana by over 5,000 kilometres (3,100 mi) of ocean. These smaller continents were also sufficiently widely separated from each other to develop distinct communities of benthic organisms.The small continent of Avalonia had just rifted from Gondwana and began to move north towards Baltica and Laurentia, opening the Rheic Ocean between Gondwana and Avalonia. Avalonia collided with Baltica towards the end of Ordovician.

WARNING! Carry on reading! Or you will die, even if you only looked at the word warning! Once there was a little boy called Joey, he was ten-years-old and he lived in a mental hospital because he posted a shitty copypasta onto a People Playground mod's comment section . He got so bad he went to kill all the staff in the hospital so the Feds decided that best idea was to get rid of him so they set up a special room to kill him, as inhumane as possible. And he sat there in agony for hours until he died. Now every week on the day of his death he returns to the person that reads this letter, on a monday night at 12:00 a.m. He creeps into your room and kills you slowly, by pegging you and watching you bleed to death. Now send this to ten other profiles on this one site, and he will haunt someone else who doesn't. This isn't fake. apparently if u copy and paste this to ten comments in the next ten minutes nothing will happen: sorry man i am not taking the risk

The first mass extinction of multicellular life (of the recognized five) was the End-Ordovician Extinction Event, with a cause undetermined, having proposals ranging from a supernova or gamma-ray burst to the formation of a ring system (which is supported by impacts occurring extremely frequently along the planet's equator during said extinction). Also, I noticed that a lot of the moons were in the wrong orbits or missing, and Mars and Venus still had oceans (although they lost their water 2.9bya and 700mya(?) respectively).

serval_serval_serval_serval the first mass extinction mainly happened during protocells if you dont count that there was one a little bit after unicell life
