  1. Geologist Link to biology via paleontology 1969-1971: Spent a year collecting fossils 1-2 days every week in eastern California

  2. Name a new species • Publish in peer-reviewed journal • Describe characteristics, and type specimen • For fossil, good preservation • Naming • For location found -- Crassostrea virginica (Gmelin, 1791) • For physical characteristic -- Crassostrea gigas from the Latingigas, "giant" • For a person (but not yourself)

  3. Focus of my work in 1969-1971 • Collect trilobites • Growth study (they molt like a crab, shedding exoskeleton) • But collect everything

  4. Eocrinoids are among the earliest groups of echinoderms to appear, ranging from the Early Cambrian to the Silurian. This one, Gogia, is from the Middle Cambrian House Range of Utah. Despite the name ("dawn crinoids"), they are not directly ancestral to the true crinoids. http://www.ucmp.berkeley.edu/echinodermata/eocrinoidea.html Found new one, and knew none had been found there previously

  6. In zoological nomenclature, synonyms are different scientific names that pertain to the same taxon, for example two names for the same species. The rule of zoological nomenclature is that the first name to be published is the senior synonym; any others are junior synonyms and should not be used. • Synonyms are "objective" if they unambiguously refer to the same taxon; this is the case if they refer to the same description or the same type specimen. Otherwise the synonyms are "subjective", meaning that there is room for debate: one researcher might consider the two names to refer to the same taxon, another might disagree.

Unpublished Ph.D. thesis, University of Victoria, 491 p., 41 pls. • Nomen Nudem- An unavailable name which therefore may be available for use at a later date. • Nomen nudem / NN Latin for "naked name" a name that is not regarded as valid because of inadequate or lost specimens on which the description is based • nomen nudem, nom. nud. or n.n. Indicates that the species in question not yet been validly described.
