Fossil Flowers and Leaves in the Naches Formation
The Mushroom Whisperer posted a topic in Fossil Hunting Trips
Plant Fossil Trip Where: Naches Formation, Central Washington State, USA Age: Considered middle Eocene to early Oligocene When: July 04, 2020 My short YouTube video of the trip: We arrived at the primary collecting site after a three hour drive through low clouds, over a 1656 m high snowy pass, and through miles of deer infested roads. On the way up, I stopped and inspected 3 other locations in the hopes of finding additional sites; one area yielded fossils! Future site! The collecting site is simply a cut bank on the side of the road, utilized by families and clubs for years. Immediately upon arriving, I started looking through, and splitting, the loose shale accumulated towards the lower level of the cut. I've always found something here, and this time was no different. A couple of whole leaf fossils and tons of bits and pieces later, I continued up the hill. I stopped at an outcropping of shale that I had found a Florissantia sp. fossil at, on the previous trip. This trip proved no different as the same area gave up five more flowers, two on one piece! After finding the flowers and keeping a couple more leaves and stems, I loaded up a small box of unsplit shale to be prepped at a future time, when the weather is bad or we get locked down again... Overall an exciting trip, and I can't wait to go again!- 4 replies

Hello everyone, I went out for another plant fossil trip, with the specific goal of finding more flowers... I believe I did! The first picture has one flower just to the left of center, and to the right I believe is another flower in profile. The second picture has a flower that appears to only have 4 petals.

I found this cool little specimen at my favorite site, a late Eocene lakebed shale deposit. See the obverse here https://drive.google.com/open?id=1jxKmyNfifvGq-3S_JKe342I7bQEp9Qnw I've tentatively identified it as florissantia sperri, most often found hours away at the Florrisant Fossil Beds. Google tells me my specimen is the flower of an ancient relative of a cocoa tree,, with the reproductive parts nicely preserved in the centre of the piece and framed by metasequoia fragments. Much more unusual is this nicely preserved fern. https://drive.google.com/open?id=1hWoNWpngzG6MlZEuZ8j23yGWu0OlSyXg It is uncharacteristically large for plants found at this site, and was recovered from the courser/crumblier matrix that almost always has nothing but black wood fragments in it. If it is sandstone, it is likely several million years younger than the supposed florissantia specimen
