INTRODUCTION The following report contains lists of the larger invertebrate fauna from 320 collections made at 267 localities or different levels at a locality in the rocks of the Haustator bilira Assemblage Zone as exposed in Texas, Arkansas, and Missouri (Figure 1). The Haustator bilira Assemblage Zone was proposed by Sohl (1977) and traced through Late Cretaceous rocks of the Atlantic and Gulf Coastal Plains from New Jersey to Texas (Owens et. al., 1977; Sohl and Smith, 1980). The base of the zone occurs above the base of the foraminiferid Globotruncana gansseri Subzone of Pessagno (1969) and* includes all subsequent younger Cretaceous deposits on the Coastal Plains.

Lists of the molluscan fauna from this zone from the East Gulf Coastal Plain are available as U.S. Geological Survey Open File Report No. 83-451.

EXPLANATION The following lists of larger invertebrates are arranged geographically beginning with the collections from localities in the northern part of the Mississippi Embayment of southeastern Missouri (Table 1) and terminates in Texas at the border with Mexico. Study of the assemblages within this zone has necessitated reevaluation of all molluscan taxa proposed in the major Upper Cretaceous faunal monographs dealing with the Coastal Plain (Conrad, 1858; Conrad, 1860; Weller, 1907; Gardner, 1916; Stephenson, 1923, 1941, 1955; Sohl, 1960 and 1964) as well as shorter contributions. Many of the earlier works on the region treated the faunas in a very provincial manner. Geographic isolation was considered in some cases ample justification for erection of new taxa. Current knowledge of the stratigraphic relationships between the Coastal Plain sequences, coupled with larger collections that allow for better understanding of variation within species, has necessitated considerable synonomization of taxa. Thus the lists reflect current thought. Similarly at the generic level, the volumes of the "Treatise on invertebrate Paleontology" devoted to the Mollusca have provided a basis for reassignment or synonymizing older usages.

EXPLANATION OF ANNOTATION

Each location has been annotated using an outline that has 15 numbered categories. A key to the format and an explanation of abbreviations used are given here. 1. Stratigraphic assignment - The name of the lithostratigraphic unit from which the collection was made. 2. Subdivision - Where determinable, assignment is made to an upper or lower part of a lithostratigraphic unit. Such designation is given in a physical sense relative to total thickness of the unit and is not necessarily tied to a precise temporal subdivision. Springfield

*equals Corsicana plus Kemp of Stephenson 1941 3. Source of collection - An indication of who made the collection and when it was made. This is a gross measure of the type of collection made. In general the earlier collections consist of selectively but generally representative samples. Collections made by the authors consist of bulk samples in which rarer taxa are more likely to occur. The U.S. Geological Survey collection numbers are given in Table 2.

4. Lithologic designation - Primary lithic type, _i^e_«, sandstone, siltstone, claystone, chalk. Categories 5 through 10 give modifying terms for the primary lithic types:

5. Color

6. Sorting 7. Miscellaneous 8. Miscellaneous

9. Mica content, if no entry, then mica was not noted. 10. Grain size For some lithic descriptions of chalks, clays and silts which are noted to be sandy, the descriptions of sorting and grain size apply to the sand fraction.

11. Shell preservation - Designation of the various modes of shell preservation: molds « external and internal impressions phosphatic molds « internal molds.

12. Latitude 13. Longitude 14. Topographic elevation of the collection locality. 15. Fauna - A listing of all larger invertebrate taxa identified in the collection studied from the locality. The taxa are arranged in the order provided by the "Treatise on Invertebrate Paleontology" for Bivalvia, the Archaeogastropoda, the Scaphopoda and Ammonoidea. The remainder of the Gastropoda follow the arrangement of Taylor and Sohl (1962). The number of specimens of each taxon in the collection is given preceding the species name. TABLE 2.
