My 25 years of palaeoart chronology...

Some zooms into my "The Salt Lake Severn" painting (2022) of the Severn Estuary during the Middle Triassic, featuring Thecodontosaurus, cycads, and ferns. Commissioned by the Clevedon Pier Trust.

My 25 years of palaeoart chronology...

Into 2022 with a painting of the Severn Estuary during the Middle Triassic, called "The Salt Lake Severn," featuring Thecodontosaurus, cycads (Dioonitocarpidium), ferns (Thaumatopteris), and dust devils.

Preparing some herbarium sheets for display in our new dinosaur gallery. All of these plant groups – a fern, cycad, and horsetails – were around during dinosaur times.

Installation of this new gallery has been a little delayed but we're planning to open in October if all goes to plan.

Cycads at the Oslo Botanical Gardens (Cycas circinalis)

#Cycas #cycads

Two large rosettes of cycad leaves, each pinnate like a feather, and attached to a tall sturdy brown trunk. Viewed from below so the light breaks through the leaves like a couple of shuttlecocks held to the ceiling

Ancient Cycads: The Dinosaur-Era Plants That “Breathed” Nitrogen To Survive Extinction
Cycads, ancient plants once prevalent during the Mesozoic Era, have mostly gone extinct, with a few species surviving in tropical and subtropical areas. Researchers have discovered that these surviving cycads relied on symbiotic bacteria for nitrogen fixation, a trait not found in their extinct counterparts.

Not unlike a giant flower bud, the emerging stems of a cycad all folded together like an onion dome with a fur collar

Dynamic plants: Origin & geographic evolution of cycads clarified

Paleobotanist have made an important breakthrough in understanding the origin and geographic distribution of cycads. By combining genetic data with leaf morphological data from both fossil and living species for the first time, the researchers created a phylogenetic tree of these fascinating and endangered plants.

Image : The African cycad Encephalartos altensteinii Lehm is widely cultivated in botanical gardens around Europe (like this one in the Botanical Garden of the University of Naples “Federico II”), including one specimen that was brought from South Africa to the UK in 1775 and that is still alive today. Large Encephalartos are highly prized as ornamental plants, and unfortunately many species have been brought to the brink of extinction by poaching. Credit: Mario Coiro

Our work on the evolutionary history of #cycads is out in @newphyt !
We built a #phylogeny with 321 extant and 60 #fossil cycads, and dispelled the myth of the 'living fossil' being left over from the age of the #dinosaurs

“#Cycads are the most threatened group of plants in the world. These ancient plants date back about 280m years, before the age of the dinosaurs, and they look primeval, with a rugged chunky trunk rising into a crown of stiff feathery leaves. Poachers can also destroy whole habitats plundering the plants, and the trafficked plants are at risk of disease. Trying to protect the cycads is highly dangerous, and rangers in Kruger national park in South Africa have been killed in order to steal the plants."

#Cycads, a group of gymnosperms which can resemble miniature palm trees (like the popular sago palm #houseplant) were long thought to be “living #fossils,” a group that had evolved minimally since the time of the dinosaurs. Now, a well-preserved 80-million-year-old pollen cone discovered in California has rewritten scientific understanding of the #plants.
