Title for my Botany 2020 presentation I attended the Botany 2020 virtual conference, where I presented a talk on fossil passionflower seeds from Gray Fossil Site. I also coauthored a poster on the phylogeny of fossil and living mosquito ferns. The talks and links to the abstracts are below: Hermsen, E.J.*  2020. Fossil  Passiflora  seeds from Gray Fossil Site (Pliocene, Tennessee, U.S.A.).  Link to abstract Jud, N.*, F. De Benedetti,  E.J. Hermsen , and M. Gandolfo. 2020.

Modern Azolla  sporophytes, cultivated The Botany 2018 meeting was held from July 21-25 in Rochester Minnesota. I was involved in two projects presented at the meeting: " Taxonomic composition of the Neogene Gray Fossil Site carpoflora (Tennessee, USA) " was presented and authored by E.J. Hermsen. " An organismal concept for fossil  Azolla  from the early Paleocene (Danian) Salamanca Formation, Patagonia, Argentina " was presented by Nathan A. Jud (Cornell University) and authored by Jud, F. De Benedetti (Museo Paleontológico Egidio Feruglio), E.J. Hermsen, and M.A. Gandolfo (Cornell). It was part of the colloquium  " Fossil plants at the intersection of evo-devo and phylogeny: Celebrating the contributions of Gar W. Rothwell to biodiversity and evolution ."

Festive sauropod skull at the Mef In early January, I traveled to Trelew, Argentina, to examine fossils from the Cretaceous La Colonia and Eocene Laguna del Hunco floras held at the Museo Paleontológico Egidio Feruglio (Mef) in Trelew, Argentina. These fossils included mosquito ferns ( Azolla ), which I am studying with colleagues María A. Gandolfo and Nathan Jud of Cornell University.
