On the left- Archaeopteris in the Smithsonian today. On the right - Prototaxites in the New York State Museum last week.
Neither supported by modern anatomicsl studies.
Long way to go with this stuff………

A couple of days in the Catskills and New York State museum. Here Bill Stein mulls over our latest theory, Prototaxites is a big halloween hand which grew out of New Yorkers front laws during Halloween, 380 million years ago.

So sorry. He was always a joy to spend time with, to watch and to read. A huge legacy.

I'm taking a look at the Rhynie Chert again, so I made a quick size chart of the plants I've already illustrated from it.
These plants are some of the earliest land #plants, being from the Early #Devonian. From left to right: Asteroxylon, Horneophyton and Aglaophyton. #paleoart #paleobotany #sciart

Very interesting - straight into next week’s year 1 lecture!

Great stuff Flint….

Did the same yesterday…..

Me!

These four trees grew in very different climates and atmospheres. Their preserved structures can provide clues about the ancient environments they once lived in.

Scientists use these specimens to chart historic climate change and make predictions about the future of our planet. 🌍
