The Great Greenfield DinoFest

Local Arts  Local History  Local Lizards (er . . . actually dinos are ancestors of birds :))

5th Annual Festival: Saturday, December 11 & 12!

Thanks everyone for another great year! The Dexter Movie and Efraim's webinar are watchable below. Look out for the final edit of Dexter and the Dinosaurs to be released in early 2022!

DinoFest, presented by Piti Theatre and PVMA, is (normally) a celebratory in-person day of performances, interactive exhibits and activities for children, dino films with live music and more celebrating our local dinosaur footprints in the Connecticut River Valley of western Massachusetts. Why? Because this is where the first scientific study in the world of dinosaur footprints took place! You can learn more on PVMA's award winning website "Impressions from a Lost World" . . . This year DinoFest will be a combo of in-person and streaming events.

Friedman is an organic farmer and beekeeper who has been involved in the environmental movement for five decades. He has worked from the arctic to Antarctica for among others, the US Fish & Wildlife Service and counts as a high point, the privilege of conducting research on the Arctic National Wildlife Refuge.
