Autor: J. Mark Erickson, Michael J. Everhart, John W. Hoganson
Publikováno v: Transactions of the Kansas Academy of Science. 118:27-40
Modern ratfish (chimaeroids) are examples of a poorly documented lineage of cartilaginous fishes that extends back to Triassic time. Here we report on the discovery of abundant remains of the callorhynchid chimaeroid Ischyodus rayhaasi Hoganson and E

FRESHWATER UNIONID BIVALVE SHELLS AS SUBSTRATA FOR TRICHOPTERA ATTACHMENT
Autor: Andrew M. W. Lawfield, J. Mark Erickson, S. George Pemberton, Murray K. Gingras
Publikováno v: PALAIOS. 29:525-532
A variety of competitive advantages accompany colonization of hard substrates in aquatic settings, and as a result, many organisms adopt this mode of life. Similarly, adverse effects may occur to organisms that have themselves been encrusted. Many ma

Autor: J. Mark Erickson, Matthew E. Burton-Kelly
Publikováno v: The Open Paleontology Journal. 3:1-13
Late Cambrian arthropod trackways from the Potsdam Sandstone have been known since the 1850s. A site in Clinton County, New York, USA, exposes Protichnites in fine-grained, quartz-rich, rippled, micro-laminated Potsdam Sandstone. The study area inclu
