Dear IOP Members, Respectfully, Mike

I am happy to report, that IOP seems to be on track and ready for a new Executive Council to take over. The elections are IPC XIV/IOPC X 2016 progressing nicely and I will report the results in the September/October Newsletter.

The one area that is still problematic is the webmaster position. We really to talk amongst ourselves, and find someone who is willing and able to do the job. I discuss the position in more detail below.

Everything seems to be falling into place for IOPC X at Salvador Brazil. The

IOPC 2020 IOP Webmaster

At this time we have no official bids to host I was very sorry to accept the resignation of IOPC2020. Alan Spencer as our Webmaster. Alan has

The IOP Executive Committee elections are underway and will be open until 30 WHAT HAS HAPPENED TO August. To date 73 members have voted for THE OHIO UNIVERSITY a participation rate of 26%. That is an even PALEOBOTANICAL worse voting rate than American elections, and I know that you don’t want to make us COLLECTIONS?

The Italian palaeobotanical heritage represents an important source of new information on the evolution of plants and the ecosystems in which they lived, but can also help in predicting future environmental scenarios. The present volume is the first general book on fossil floras of Italy; it is bilingual with an Italian and English text. The book is divided in a detailed overview on the history of palaeobotany in Italy, a general part on materials and methods in palaeo- and archeobotany and nine chronological chapters (from the Carboniferous to Archeobotany). Each chapter is divided in The 10th European Palaeobotany and geographic areas as well as in macro- and Palynology Conferencewill be held in microfloras.

La storia delle piante fossili in Italia, seconda edizione - Paleobotany of Italy, second edition 25th International Workshop on Plant Evelyn Kustatscher, Guido Roghi, Adele Taphonomy 2015, November 25 - 26, Bertini & Antonella Miola (eds.) 2015, Bonn, Germany Veröffentlichungen des Naturmuseums

Südtirol, volume 9 pp. 400, 20.6 x 27.6 cm, Euro 25,00 The 25th International Workshop on Plant Bozen/Bolzano, Naturmuseum Taphonomy will be held on the last Südtirol/Museo di Scienze Naturali weekend in November in Bonn, from dell’Alto Adige 2016 Friday, November 25 to Saturday, ISBN: 978-88-87108-09-5 November 26, 2016. The date provides terrific opportunities for stimulating UPCOMING MEETINGS discussions over Glühwein at the Bonn I OP 110 15 August 2016 Christmas Market, so please mark it on Cameron University your calendar! The 2016 workshop will Lawton, Oklahoma 73505 feature a keynote lecture from Robert Ph.: 580-581-2287 Gastaldo (Colby College, Maine, USA) on email: [email protected] “Time, Space, Sedimentary Systems, and Some Thoughts on Geochemistry of Why, or Not, We Have A Fossil Plant Record,” as well as a round-table discussion on the taphonomy of leaf cuticle led by Lutz Kunzmann (Senckenberg Naturhistorische Sammlungen Dresden, Germany). Contributed talks and posters on all aspects of plant taphonomy are welcome.

Although there will be formal presentations, we hope that the meeting will retain its informal, discussion-oriented, workshop flavor, and students and new members wanting to check out plant taphonomy are especially wanted. The deadline for pre-registration and abstracts is October 1, and more information will be contained in a second mailing at the end of summer. If you are interested in receiving this second circular or if you have any questions, please send an email to Carole Gee ([email protected]).
