In #Carboniferous, global #forests appeared, covering #tropical zones with tree-high #horsetails, #clubmosses, and #ferns. #Oxygen levels rose, and #CO2 was bound for transforming peat into lignite and #bituminous #coal. The climate later became colder i.a. due to the decreasing greenhouse gas leading to the Permo-Carboniferous Ice Age period.

Plants struggled for millions of years after the world's worst climate catastrophe
https://phys.org/news/2025-03-struggled-millions-years-world-worst.html

"#conifers were some of the earliest to colonize the land after the End-#Permian catastrophe. But the recovery of #forests was not smooth sailing... even higher temperatures during the Late Smithian Thermal Maximum caused the collapse of these survivors... they were replaced by tough, shrubby #plants resembling modern #clubmosses. This scorching period lasted for about 700,000 years"

#FossilAdventCalendar Day 3

We're jumping to the #Maritimes today to celebrate one of #Canada's 🇨🇦 most important #fossil sites. #NovaScotia's #JogginsFossilCliffs are a window into the #Carboniferous, a period that saw the spread of a new #biome: #forests. This #fossilized #tree on display at the #RoyalOntarioMuseum is a #lycopsid, a super-sized relative of living #ClubMosses that, along with #cycads, #ferns, and early relatives of #seed #plants, made up the #flora of the #Joggins #forest.

Lepidodendron yorkianum from the Carboniferous (from #BritishGeologicalSurvey R.L. Kidston photo collection). Looking similar to one of today's clubmosses http://geoscenic.bgs.ac.uk/asset-bank/action/viewAsset?id=63645
