These Triassic fossil cycads absolutely blow me away every time I see them.

Fabulous photos showing the mutualism between #cycads and #cyanobacteria. Those dark bands inside the roots are colonies of nitrogen-fixing cyanobacteria. #Cyadaceae #Zamiaceae https://twitter.com/megetra/status/1636493997488193538

CLIFF HANGERS!
I love #cycads. Here is Cycas clavicola, a relatively new Indonesian species (1999) that can grow on cliffs.

A sign of the times. In the UK, "male and female sago palm cycads are producing cones at the same time outdoors. This means that cycads will be able to successfully reproduce at this latitude since at least the Cretaceous Period, roughly 120 million years ago."
