>University of Texas Press just published an interactive cd-rom called >"Thranaxodon" Actually, it is Thrinaxodon. For those who have WWW clients (like Mosaic), the UC Museum of Paleontology server has information and images showcasing this CD-ROM. I will be happy to point out the exact location on the server to those interested. Thrinaxodon is a non-mammalian synapsid that has many interesting cranial features showing movement toward the mammalian condition.
