Dr. James E. Conkin and Prof. Barbara M. Conkin gave permission to use all their work in the Foraminifera.eu Project. We intend in 2012/2013 to make the outstanding work of the Conkins on Paleozoic Foraminifera accessible. We will integrate all available images and drawings. Specimens from the Conkins collection will be photographed. We will put available publications online or place links such as to their articles in Micropaleontology.

We deeply appreciate this most valuable contribution and the great help of Michael Popp, Louisville Fossil Blog, who made the contact and this project possible.           Michael Hesemann, March 2012.
