We think that the complex relationships that exist between Idiognathodus and Streptognathodus must be investigated from the inception of these morphologies, from Morrowan and Atokan
time, and that all troughed and partially troughed forms prior to Missourian should be excluded from Streptognathodus.
Their topics include Lower Cambrian shelled phosphorites from the northern Montaigne Noire in France, Siluro-Devonian alpine reefs and pavements, a late Atokan
regional encrinite in the Sierra Agua Verde in northwestern Mexico, and whether the distribution of tabulae in tabulates can be used to estimate palaeo-environmental changes.
Unit owns interests in 47 Buzzard Gap wells which produce from several Atokan
age sandstones and have produced approximately 83.
Serendipitously, the project may also encounter oil and gas in the Atokan
Conglomerates, the Caddo Limestone, the Strawn Sands and the Cisco Sands.
The company's conventional drilling program in the Arkoma includes the traditional "Fairway" area of the basin where the company has historically targeted the conventional Atokan
objectives and the Ranger Anticline area which is located at the southern edge of the Arkansas portion of the basin.
The well targeted the lower Atokan
