Meekoceras Ammonoid Fossil

This ammonoid fossil appears to be a Meekoceras sp. It was found in the Thaynes Formation of Salt Lake County, Utah. It dates to early Triassic Period.

Thanks to Nathan for this fossil. Recently, he visited the Louisville area with a group of students from the University of Wisconsin and we exchanged some fossils. They were very dedicated and impressive in their fossil searching capabilities. We visited a number of local sites and collected for hours in the rain, sleet and snow. Brrr, it was cold and wet. Lots of neat fossils were found, including a Silurian cystoid, a spiny brachiopod, trilobite segments, a giant snail, colonial coral colony, and lots of ziplock bags of fossils. After Louisville, they had more areas to visit around the midwest to find fossils at.

Palmoxylon Fossil

This fossil appears to be of the genus Palmoxylon and was found in Texas. It is from the Eocene. Fossil was photographed wet and magnified 40x and 100x which is about 6mm and 1mm field of view.

Thanks to Herb for the fossil.

Palmoxylon Fossil Magnified

These magnifications are from a thin slab of silicified palm fossil. I wet sanded the slab with 320 and 800 grit paper. Karate Kid's Mr. Miyagi would be proud of my sanding work!

Fossil was photographed wet to enhance the contrast. Have not tried polishing it yet.
