Birthday cake celebrating Mary Anning From May 13th to May 17th, I had the privilege of visiting the collections of Gray Fossil Site again in order to pick through unsorted fruits and seeds. I gave a talk on the Gray Fossil Site carpofossil flora on May 15th, I sorted a lot of material, and I had some cake!
