Tapeworm Eggs in a 270 Million-Year-Old Shark Coprolite

Creator:: Dentzien-Dias, Paula C., Poinar, George, Jr., de Figueiredo, Ana Emilia Q., Pacheco, Ana Carolina L., Horn, Bruno L. D., and Schultz, Cesar L.
Abstract:: Remains of parasites in vertebrates are rare from the Mesozoic and Paleozoic. Once most parasites that live in - or pass through - the gastrointestinal tract of vertebrates, fossil feces (coprolites) or even intestinal contents (enterolites) can eventually preserve their remains. Here we announce the discovery of a spiral shark...

Eocene and not Cretaceous origin of spider wasps: Fossil evidence from amber

Creator:: Rodriguez, Juanita, Waichert, Cecilia, von Dohlen, Carol D., Poinar, George, Jr., and Pitts, James P.
Abstract:: Spider wasps had long been proposed to originate in the mid-Cretaceous based on the Burmese amber fossil Bryopompilus interfector Engel and Grimaldi, 2006. We performed a morphological examination of this fossil and determined it does not belong to Pompilidae or any other described hymenopteran family. Instead, we place it in...

Silica bodies in the Early Cretaceous Programinis laminatus (Angiospermae: Poales)

Creator:: Poinar, George, Jr.
Abstract:: Silica bodies in short cell epidermal leaf cells of the Early Cretaceous Programinis laminatus (Poales) in Burmese amber are characterized. The great majority are rondels and elongated quadrates aligned horizontally in relation to the leaf axis. Rondel types include circular, elliptical, oblong, long and short forms. Quadrate types include short...

Tripius gyraloura n. sp. (Aphelenchoidea: Sphaerulariidae) parasitic in the gall midge Lasioptera donacis Coutin (Diptera: Cecidomyiidae)

Creator:: Poinar, George, Jr. and Thomas, Donald B.
Abstract:: A new nematode, Tripius gyraloura n. sp., is described from the arundo gall midge, Lasioptera donacis Coutin (Diptera: Cecidomyiidae). This gall midge is being considered as a biological control agent for use in North America against the introduced giant reed Arundo donax (L.) (Poaceae: Cyperales). Thus the present study was...
