  Homalonotus - trilobite - Smithsonian Museum of Natural History - 2012-05-17
  A fossil Homalonotus on display in the Sant Hall of Oceans in the Smithsonian Museum of Natural History.
  Homolonotus is a species of trilobite. Trilobites are arthropods, a kind of animal that includes shrimp, lobsters, scorpions, crabs, and crayfish. Trilobites first appeared about 542 million years ago (the early Cambrian period), but most of them died out around 360 million years ago. One or two species survived until 250 million years ago.
  Trilobites were wildly successful animals. More than 17,000 species are known today.
  Homolonotus appeared about 444 million years ago, and died out about 416 million million years ago. This specimen was discovered by Bruce Collette and two assistants in Madagascar in 1987. We know next to nothing about how it lived.
  The hall is named for Victoria and Roger Sant of Washington, D.C., who donated million to create and endow the hall. It opened in 2008. The exhibits, displays, videos, and signage in the hall was created in partnership with the U.S. National Oceanic and Atmospheric Administration (NOAA) to show the ocean as a global system.
