  • New Contributions to Paleobiology publication!

    Late Pleistocene (Rancholabrean) Mammalian Assemblage from Paw Paw Cove, Tilghman Island, Maryland
    Late Pleistocene (Rancholabrean) Mammalian Assemblage from Paw Paw Cove, Tilghman Island, Maryland
    Ralph E. Eshelman, Darrin Lowery, Frederick Grady, Dan Wagner, H. Gregory McDonald (Author)

    Smithsonian paleontologists discover the first tooth of giant beaver found in Maryland, recovered from Chesapeake Bay's Tilghman Island, which is being devoured by wave erosion. Read about this and their other amazing prehistoric finds in SISP's newest paleobiology publication.

    Phymatolithon (Melobesioideae, Hapalidiales) in the Boreal–Subarctic Transition Zone of the North Atlantic: A Correlation of Plastid DNA Markers with Morpho-Anatomy, Ecology, and Biogeography
    Phymatolithon (Melobesioideae, Hapalidiales) in the Boreal–Subarctic Transition Zone of the North Atlantic: A Correlation of Plastid DNA Markers with Morpho-Anatomy, Ecology, and Biogeography
    Walter H. Adey, Jazmin J. Hernandez-Kantun, Paul W. Gabrielson, Merinda C. Nash, Lee-Ann C. Hayek (Author)

    Species of coralline algae of the genus Phymatolithon that occur in the Boreal–Subarctic transition zone of the North Atlantic are  segregated systematically by a statistical/developmental analysis of their morpho-anatomical characters. Variations in vegetative tissue morphology, particularly with respect to cell division and elongation patterns, as well as variation in conceptacle (reproductive structure) location and development, are the result of a complex of genetic and environmental factors.
