Type Image Repository

This is a currently small collection of digital images of type specimens of various palynomorph species. Holotypes are the most important images, but a few images of similar specimens from the same or closely related samples are also included. I will soon be adding additional type material images from Singh (1971, 1983), Brideaux (1977), and others.

I offer these images in the hopes that other people will freely make images available of the type material they have access to. Digital images and the world-wide-web make it possible to quickly and cheaply share paleontological information, and sharing of type images could potentially save a great deal of expense and inconvenience during palynological studies. They can not substitute for direct observation, but are an excellent starting point.

I will gratefully accept any type specimen images people are willing to deposit here, or any links to images of palynological type material. If you send images, I will add your name as the copyright holder, and assume the distribution restrictions stated at the bottom of this document (freely distributable for non-commercial purposes) unless you specify otherwise.
