British Carboniferous Fossil Plants & Leaves – Coal Measures UK, Authentic Paleozoic Specimen

An outstanding collection piece featuring authentic British Carboniferous Fossil Plants and Leaves from the classic Coal Measures deposits of the Carboniferous Period, approximately 310–320 million years ago. These fossils were formed in the lush, swampy forests that once dominated prehistoric Britain, now preserved as detailed impressions in shale or siltstone.

The fossil assemblage typically includes various species of ferns (Neuropteris, Alethopteris), seed ferns (Pecopteris), lycopsids (Lepidodendron, Sigillaria), and horsetails (Calamites), representing the dominant vegetation of the time.

Fossil Type: Fossilised Plant Impressions (Leaves, Stems, and Fronds)

Geological Age: Carboniferous – Pennsylvanian Subperiod (Westphalian Stage)

Formation: Coal Measures (Upper Carboniferous)

Depositional Environment: These plants grew in lowland tropical wetlands and coal-forming swamps. Rapid burial by sediment in oxygen-poor environments led to remarkable preservation of delicate plant structures in fine-grained muds and silts.

Morphological Features:

Detailed vein and frond impressions

Often preserved as flat carbon films or positive/negative moulds

Fronds may show branching patterns and midrib structures

Notable:

Fossils from the iconic British Coal Measures

Includes representatives of extinct tree-sized club mosses and seed ferns

Excellent for educational use, fossil collectors, and display

Actual specimen photographed – scale rule = 1cm per square

Authenticity: All of our fossils are 100% genuine natural specimens and are supplied with a Certificate of Authenticity. The photo displays the exact specimen offered. Please refer to the image for full dimensions.

This fossilised record of ancient forest life offers an incredible window into Earth’s prehistoric ecosystems. A classic and educational specimen from the Carboniferous coal-forming landscapes of the UK.

going to be devastatingly real. i don’t care about the paleozoic. i don’t care about the cambrian explosion. the carboniferous rainforest collapse is MAYBE intriguing at best and goddamn if i don’t get tired hearing about fucking lepidodendron “trees.” mesozoic and cenozoic always win >>>>

If a frilled shark and a fern were to fight each other who do you think would win /genq

hold on i have to google

WTFF ok ok imma be serious here

its gonna have to go to fern bc no way is that shark getting onto land. if this was a tiktaalik vs fern fight that'd be a different story.

but i am giving the win to the fern because she can populate land like crazyyy and have strong defense system meanwhile silly frilled shark is stuck in the water with no good bone structure in its fins

Plants Surviving the Worst Mass Extinction

ESP Version ITA Version

When we think of mass extinctions, we often imagine the meteorite impact that killed the dinosaurs at the end of the Cretaceous, 65 million years ago. However, the greatest extinction event occurred between the Permian and Triassic periods, around 250 million years ago, eliminating over 96% of marine species and about 70% of terrestrial vertebrates. But how did plants fare?

According to a study conducted by University College Cork, the University of Connecticut, and the Natural History Museum of Vienna, plants did not experience a mass extinction comparable to that of animals. Nevertheless, their communities were severely impacted or even completely destroyed due to extreme climatic conditions: intense heat, drought, depletion of the ozone layer, widespread wildfires, and contamination by toxic heavy metals.

The study analyzed fossils from the Sydney Basin in eastern Australia, which at the time was located near the South Pole. Researchers gathered sedimentological data (physical, chemical, and depositional characteristics of sediments), biostratigraphic data (fossil distribution within rock layers), and stable carbon isotope ratios from organic matter, reconstructing environmental conditions of that era.

Fossils revealed that the first plants to recolonize devastated landscapes were conifers. Unfortunately, these conifers did not survive a subsequent period of extreme heat known as the Late Smithian Thermal Maximum, which lasted around 700,000 years. In this hostile environment, stress-tolerant, cosmopolitan lycophytes, similar to modern clubmosses, became dominant. Later, during a cooling event (Smithian-Spathian event), large and unusual seed ferns (such as "umkomasialea") emerged, gradually forming more stable and lush forests. These plants laid the foundation for the Mesozoic dinosaur era and the immense fern-dominated forests that persist in our collective imagination.

This research underscores the importance of protecting modern forests because, as the authors emphasize, "forests eventually recover, but the extinction of individual species is forever." Complete ecosystem recovery takes millions of years, and preserving today's plants ensures stability for future food webs and climate systems.

Spinosaurus Aegyptiacus 🦖☄️

Was thinking of getting another tattoo and sketched something ideal of what I’d like, the Spinosaurus is one of my favorites, I might draw a Utahraptor design too eventually :)

I’ve been posting a lot of Regretevator lately so this is something different
