Mark McMenamin is a tenured professor of geology at Mount Holyoke College. His research is primarily focused on paleontology, particularly the Ediacaran biota.

He is the author of several books, most recently The Garden of Ediacara: Discovering the Earliest Complex Life and Science 101: Geology. He is credited with co-naming several geological formations in Mexico, describing several new fossil genera and species, and naming the Precambrian supercontinent Rodinia. The Cambrian archeocyathid species Markocyathus clementensis was named in his honor in 1989.

Research and theories

McMenamin's work on the paleoecology of the Cambrian explosion showed that trilobites belonging to the Agnostida may have had a predatory lifestyle. McMenamin's research on the Phoenician world map helped to inspire Clive Cussler and Paul Kemprecos's 2007 novel The Navigator, and his Garden of Ediacara theory helped to inspire Greg Bear's novel Vitals.

Prehistoric "kraken"

Mark McMenamin and Dianna Schulte McMenamin argued that a formation of multiple ichthyosaur fossils (belonging to the genus Shonisaurus) placed together at Berlin–Ichthyosaur State Park may represent evidence of a gigantic cephalopod or Triassic Kraken that killed the ichthyosaurs and intentionally arranged their bones in the unusual pattern seen at the site.[2][3]

Opponents have challenged the theory as too far-fetched to be credible.[4][5] PZ Myers believes that the rows of vertebral discs may simply be a result of the ichthyosaurs having fallen to one side or the other after death and rotting in that position, while Ryosuke Motani, a paleontologist at the University of California, Davis, has alternately proposed that the bones may have been moved together by ocean currents because of their circular shape.[6] McMenamin has dismissed both of these concerns as not being in accord with either the sequence of bone placement or the hydrodynamics of the site. [7]
