Sometimes important fossils are #TeenyTinyThings - like this 200 million year old Tritheledont tooth that was collected during a public fossil dig at Wasson Bluff in 2016. The tooth is from an extinct mouse sized animal (10-20 cm) that was a close relative to early mammals.

For #FossilFriday - a 300 million year old Neuropteris frond that was found yesterday during a site survey on the northern shore of #NovaScotia. Summer sunshine illuminates and warms an ancient fern leaf again after 300 million years. The beauty of natural history in this present moment. ⚒️

It is a rainy day in Nova Scotia. These impressions were made by raindrops falling millions of years ago, a prehistoric weather event frozen in the fossil record. Check out another Fossil Rain Print on our Collection Online: collections.novascotia.ca/object-967gs...

In 1832, Jacob Green MD was the FIRST to illustrate and describe a fossil from #NovaScotia - Asaphus crypturus, a giant Devonian trilobite from #MooseRiver at #Clementsport. Green also made plaster reference casts shared with museums around the world. He obtained the fossi from Francis Alger.

On my desk for #FossilFriday - these small bones (Northern Leopard Frog) and the spruce cone being removed from a small block of 80,000 year old mud collected during the 1991 Mastodon dig. These have been in a freezer for over 30 years! Will the 80,000 year old spruce cone have viable seeds?
