Small, Old, Dead Things

9 May 2010

A few weeks ago I shared a trick (I guess the cool kids call these ‘hacks’) that I learned from Alex Wild for getting decent makeshift macro shots with a cell-phone camera. By placing a magnifying lens in front of the camera lens, one can shorten the focal length of the phone camera allowing decent close-up shots of relatively small objects.

Lately the geobloggers have picked up on this technique, not surprisingly as geologists tend to always have a hand lens at the ready, and posted some great closeup shots of, well, rocks. Mountain Beltway started the trend (I guess the cool kids call these ‘memes’), Highly Allochthonous and Looking for Detachment have posted some nice comparison shots illustrating the potential, and limitations, of this technique.

I’ve been playing with this a lot over the last few weeks – mostly with bugs but also getting some nice atmospheric (I guess the cool kids would say ‘pornographic’) floral shots.

Inspired by Callan and co. I decided to turn my lenses toward the various bits of small, dead, old things scattered around our house. My mom asked for a rock for Mother’s Day, so, until I get one in the mail these will have to suffice.

I’m to lazy to ID these right now, so have fun guessing in the comments:

    that first one intrigues me, but the rest include assorted trace fossils, bryozoans, an ammonite, internal casts of gastropods, a brachiopod, crinoid stems, and what I suspect are giant foraminiferans

  2. Drhoz Says:

    oh, and a shark tooth, of course. The last one makes me suspicious

  3. Neil Says:

    Pretty much a clean sweep, albeit at a fairly coarse taxonomic resolution. The first is interesting. And the last one is legit – I found it.

    • Drhoz Says:

      it’s real? Astonishing! Must have been unusual preservation conditions to have a reverse cast of the bones, that intact. Any idea what it was?

      Is the first a mantis shrimp, by any chance? and the second a heteroconch ammonite?

  4. Neil Says:

    It’s an external mold of the left limb of Keichousaurus.

    Mantis shrimp is a good guess for the first one, it is indeed a crustacean, but a Mysidacean, I think the genus is Schrimperella.

    The second is an external mold of some type of crinoid, though I am not sure of a more specific identity than that.
