were selected from surface sediment samples with fine brushes.
Sediment was sampled using either an Ekman dredge or a piston corer with a five-inch diameter plastic tube, and in both cases the uppermost 1-2 cm of sediment was subsampled for ostracode
Detritus within coral intraskeletal pores is significantly finer, consisting mostly of mudstone with minor silt-size skeletal components (including ostracodes
Following fixation and staining, the epidermis of each ostracode
was dissected and allowed to air dry on a microscope slide for at least 1 h before scanning at 1000x magnification.
Temporal and spatial distribution of ostracodes
across the Pennsylvanian-Permian boundary interval in eastern North America.
(1987): Analyse quantitative de la distribution des ostracodes
et de leurs gisements dans le bassin eocretace d'Oliete (Espagne).
Wavy-bedded, skeletal grain- to wackestones (packstone dominating) with numerous rounded skeletons of stromatoporoids, corals, and rare calcareous algae, oncolites, gastropods, and lepertitide ostracodes
The grainstone is composed of about 80 percent ooids nucleated on a variety of bioclasts that include crinozoans, bryozoans, trilobites and ostracodes
. At some levels peloids and grapestone textures occur.
baccata, the ostracode
Plicibeyrichia numerosa and the thelodont T.
They come from grey and greenish-grey limestones with thin interlayers of clay containing also ostracodes
, bivalves, and scales of thelodonts, fragments of osteostracans and anaspids.
-- We report three ostracode
species from the Tecovas Formation near Kalgary, Crosby Co., Texas: one species of Darwinula, one species of Gerdalia, and a large, unidentified ostracode
zones were identified based on changes in major taxa abundance of LGH-5.
