A monograph on New Mexico fossils from the Special Papers in
Palaeontology
The non-marine, trace fossils in New Mexico are the subject of this
publication. Ichnology of an Early Permian Intertidal Flat: The Robledo
Mountain Formation of Southern New Mexico describes and illustrates
both the invertebrate and vertebrate trace fossils found in an upper
intertidal flat setting. Eighteen invertebrate ichnogenera are
described. Previously described vertebrate ichnogenera and ichnospecies
are reviewed, along with a description of a new ichnospecies.
