Pteridophyte Collections Consortium TCN

We are the Pteridophyte Collections Consortium TCN digitizing extant and fossil pteridophytes from 37 herbaria and museums. NSF funded, tweets our own.

Happy #fossilfriday! This semester we welcomed Shinju to our PCC Team Fern @ucmpberkeley. #FernFriday #fossils #fern

Happy #FossilFriday #FernFriday! Always wondered what would happen if someone pulled the poorly-engineered safety shower down the hallway. Rough week to end the semester, but Team Fern @ucmpberkeley carries on! #paleontology #digitization

Happy #FossilFriday #FernFriday! A fossil fern from Down Under. Cladophlebis albertsii from the Triassic of Australia @ucmpberkeley. Specimen on the right is the distal portion to the piece on the left that broke off when it was collected. #fossil #paleontology #digitization

Happy #FossilFriday #FernFriday! Permineralized roots of the extinct marattialean tree fern Psaronius three-dimensionally preserved in a #Carboniferous coal ball from Illinois @ucmpberkeley. #fossil #paleontology #digitization

Happy #FossilFriday #FernFriday! Asterotheca arborescens from the Permian of Zimbabwe, Africa @ucmpberkeley. #fossil #paleontology #digitization

[Pteridophyte Collections Consortium TCN @pterido_TCN]

Happy #FossilFriday #FernFriday! Together forever @ucmpberkeley - extinct species of the marattialean fern Pecopteris and extinct genus Sphenophyllum from Pennsylvania. #fossils #ferns #paleontology #digitization

@duckinwales @ucmpberkeley Coal balls are plant-rich calcium carbonate nodules that formed in coal swamps. Etching them in weak HCl acid solution leaves the plant walls standing in relief. We flood surface with acetone lay sheet of acetate over it, acetone melts the acetate, let it dry, then pull it off.

Happy #FossilFriday #FernFriday! Team Fern @ucmpberkeley got to make coal ball peels this week. Never. Gets. Old. #fossil #digitization #paleontology

[Pteridophyte Collections Consortium TCN @pterido_TCN]

@raistlinorr @ucmpberkeley It is awesome :) Thanks for liking!

[Pteridophyte Collections Consortium TCN @pterido_TCN]

@1dactylus @ucmpberkeley You can make peels that are literally just a few cell layers thick. It is amazing! Thanks for liking!

Happy #FossilFriday #FernFriday! An extinct horsetail relative, Sphenophyllum filiculme, from the Late Pennsylvanian of West Virginia @ucmpberkeley. #fossils #ferns #paleontology #digitization

Happy #FossilFriday #FernFriday! Coal ball peels don’t always cooperate…but Alex recovered very nicely @ucmpberkeley. #fossil #ferns #paleontology #digitization

Happy #FossilFriday #FernFriday! Really great to have Team Fern back @ucmpberkeley after our Winter break. #fossil #digitization #paleontology

[Pteridophyte Collections Consortium TCN @pterido_TCN]

Happy #FossilFriday, #FernFriday! UCMP Team Fern is back and in-person. Putting away last semester’s #fossil #ferns to get ready for the new ones. @ucmpberkeley #paleontology #digitization

[Pteridophyte Collections Consortium TCN @pterido_TCN]

Happy #FossilFriday #FernFriday! Thanks to Amy K. at UC Jepson and University Herbaria for hosting UCMP Team Fern’s herbarium excursion to see the #digitization of “recently dead” #ferns. @AskACABotanist @ucmpberkeley

[Pteridophyte Collections Consortium TCN @pterido_TCN]

Happy #FossilFriday #FernFriday! #ferns from Arizona’s #Mesozoic past @ucmpberkeley - Phlebopteris smithii and Cladophlebis daughertyi from the Triassic Chinle FM. #fossil #paleontology #digitization
