He even dabbled in theology with books like Science and the Bible: A Review of the Six Days of Creation (1856). He made numerous important geological observations in Hawaii and the Pacific Northwest that he later published in books and papers. For four years he served in the United States Exploring Expedition in the Pacific region. After graduating from college he had a cool job teaching midshipmen in the US Navy, sailing through the Mediterranean in the process. Dana was born in Utica, New York, and attended Yale College, working under Benjamin Silliman, a famous chemist and mineralogist. He had an affinity for “Zoophytes” (animals that appear to be plants), thus entangled him briefly with bryozoan systematics. Dana (shown above in 1858) studied geology on scales from crystal structures to continents, with volcanoes and mountain-building in between.

He is best known for his Manual of Mineralogy (1848) which is still in print (greatly revised) and known as “Dana’s Mineralogy”. I was surprised to learn that Constellaria was named in 1846 by James Dwight Dana (1813-1895), one of the most accomplished American scientists of the 19th Century. (The name Constellaria is clever.) This genus is a cystoporate bryozoan in the Family Constellariidae.
In Constellaria some of the zooecia are regularly grouped together and raised into star-shaped bumps called monticules. based in Delhi, ONTARIO (CANADA) GreenBug Energy designs, manufactures, installs, operates and maintains Archimedes screw generators for low head micro hydro sites and related industrial energy recovery applications between 1 and 500kW in size. Like all bryozooans, it was a colonial invertebrate with hundreds of filter-feeding individuals ( zooids) housed in tiny tubes called zooecia. It was found by Jacob Nowell at the Caesar Creek Emergency Spillway in the Liberty Formation.Ĭonstellaria is a beautiful form, and one of the easiest bryozoans to recognize. They did so well this week that I may be choosing a few more later! Our Fossil of the Week is the above bryozoan given the beautiful name Constellaria polystomella Nicholson, 1875.
