DELTA is no more, and certainly no less, than the sum of its members and supporters, which includes both formal institutional members and Voice from the Past subscribers. The core goal of the DELTA system is to be of service to the profession of paleontology/paleobiology; especially in the context of collaborative research. So, if you have any thoughts suggestions, corrections or complaints about anything you've seen here, please get in touch with me, Ariana Xu. I'm not hard to find, but this form constitutes a quick and easy way to do so. I'm always eager to hear from you and I never let a communication go unresponded to.
