    A couple of photos of the plates from last Friday. I just love the stereom microstructure.

    An ophiuroid vertebra (the core of the arm). This element is two fused plates. You can see the suture along the midline.
    An ophiuroid spine. All echinoderm plates are single crystals of Mg-Calcite regardless of the microstructure.

    , or Brittle Stars, are an interesting group of that have a poor fossil record. As fossils, they are often studied from isolated arm plates found in washed sediment. Here is a before and after photo of one such beast.

    Whole specimen, view about 2 cm across.
    Isolate arm plates, view about 5 mm across.

    Dogs have four kinds of teeth, incisors, canines, premolars, and molars. These are the same kinds of teeth that humans have! We love using human comparisons for because everybody understands how their teeth work!

    w/ *Uintatherium* an plant eating () mammal that lived during the (~45-37 million years ago). *Uintatherium* translates to "Beast of the Uinta ".

    Large replica skeleton of Uintatherium an extinct plant eating animal. The skull is weirdly shaped and the total size is a bit larger than a rhino, being almost 2 tons full grown.
    Close up of the skull that has concave elements. Saber-toothed canines similar to large cats but rest of the teeth are like rhinos!
    Reconstruction of this extinct beast, looks like a rhinoceros-hippo hybrid!
