This is a very beautiful Rhacophyllum cornutum (see Mazon Monday #266) from the Mazon River. Lil Magnusson showed me this stunner at the spring 2026 Danville field trip. Lil turned 85 this year and is a long-time ESCONI member… She joined in the 1960’s and rarely misses our Braceville and Danville field trips.

Here she is volunteering with Chris Cozart at the 2025 ESCONI Gem, Mineral, and Fossil Show.

And, here again at the 2025 CGMA show.

Thanks for sharing this beautiful fossil, Lil!
