Middle Jurassic (Callovian) radiolarians from carbonate concretions, Alaska and Oregon
Blome CD. 1984. Middle Jurassic (Callovian) radiolarians from carbonate concretions, Alaska and Oregon. Micropaleontology. 30(4):343-389
Limestone samples containing well-preserved radiolarian faunas were collected from strata of middle Callovian age in the Shelikof Formation between Puale Bay and Wide Bay and from the Lonesome Formation in east-central Oregon. All samples can be directly correlated to ammonite biostratigraphy. Forty-five species and 14 genera are discussed. One new genus (Milax) and 22 new species are described. The article includes 16 plates illustrating all new taxa described (316 high-quality figures) using scanning electron microscopy and transmitted light photomicroscopy.
