Plant Evolution Through Geological Time

  • 04 Aug 2021
  • 7:00 PM - 8:00 PM
  • Natural History Society of MD, Online via Zoom


(depends on selected options)

Base fee:


Take a 2 billion year journey of plants through the fossil record starting with cyanobacteria and algae to the movement of plants out of the sea onto land where the development of woody structures let them move inland and start the “greening of the earth.”  We will look at changes in reproductive methods from spore release to seeded plants such as ginkgoes and conifers to flowering plants which colored the globe ending with  the emergence of grasses that feed both long legged grazers and humans. Presented by NHSM’s intellectual treasure,  Tom Piscitelli.
Welcome to hybrid programming which will allow those who are willing and able to meet in person to do so, but also allow others who would rather learn from home, to do so as well.
Meeting Formats – NOTE: non-members are welcome to attend. A $5 donation is suggested.
  • In-person at the NHSM museum (6908 Belair Rd, 21206) – If you are vaccinated, the choice of wearing a mask will be left to you. If you or your child are not vaccinated, masks are required when indoors.
  • Online via Zoom

Doors will open at 6:30pm. The meeting will begin at 7:00pm. Again we ask for your patience as we navigate the challenges of a hybrid system. Everyone will receive the Zoom meeting details, just in case. We know the date is not the typical meeting date. There was a conflict. Thank you for your flexibility.

Natural History Society of Maryland’s Fossil Club is a group of novice and more experienced collectors will meet to exchange knowledge and help with fossil identification, discuss fossil locations, as well as other fossil related topics. Monthly meetings are held the first Wednesday of every month at the Natural History Society of Maryland. Due to COVID, NHSM is opening up this club meeting to all. Non-members are asked to donate $5. If you are a fossil enthusiast, please consider joining ( The Natural History Society of Maryland is a volunteer-led non-profit organization, so the fee you pay will go directly to support the programs, the nature collections, and the building that make this kind of nature education possible
The Natural History Society of Maryland is a 501(c)(3) non-profit corporation and contributions are tax-deductible.

The mission of the Natural History Society of Maryland is to foster stewardship of Maryland’s natural heritage by conserving its natural history collections, educating its citizenry, and inspiring its youth to pursue careers in the natural sciences.
