psiloceras planorbis (Ammonite Fossil)

Newer Older

A large and wondrous fossil specimen, seen in the booth for Chris Moore at the Arizona Mineral & Fossil Show in Tucson, Arizona. This capture was in available light inside a vendor booth at the Ramada Ltd. I've never seen such fossils and certainly never knew that the ammonites I have collected for years had their earliest ancestor in these. The ammonites evolved into squid and mollusks. The identification labels these as "Lower Lias, lower Jurassic".The slabs were found in Somerset, England in shale. The colors are natural and there is only a bit of varnish to protect the nacre which is iridescent and glows. For more about this specimen, see the link below for the psiloceras planorbis:

    Fossils are so intriguing! It's hard to imagine a world where such creatures were commonplace. Although, some of the deep sea animals that are being discovered today are pretty strange still!!
