flute, clarinet, violin, cello, piano and percussion - 10 min.

Program Notes:

This work is named after a late Jurassic-age predecessor to modern birds. The first movement is titled "Zoogenesis," which is a rarely used biological term referring to the evolution of animals. The material in this section evokes images of a profusion of ancient beasts -- both land and air born. "Fossilization" was chosen for the second movement because the musical material becomes metamorphosed and compressed in the same way fossils are formed. "Orogenesis," the title of the third movement, is the geological term for mountain building. The musical material goes through a series of metric upheavals in a fashion somewhat analogous to geologic faulting.

Musically, the work strives to synthesize myriad influences from the twentieth and twenty-first centuries, including Oliver Messiaen, Igor Stravinsky, Conlon Nancarrow, Gyorgy Ligeti, Michael Gordon, Frank Zappa, George Crumb, and others. The work also contains imports from other arts, including several instances of humorous deus ex machina.
