A correlation of the Upper Albian to basal Coniacian sequences of northwest Europe, Texas and the United States Western Interior

Journal article

From the base of the middle Cenomanian to the top of the Turonian, there are 27 zonal units recognizable in the Western Interior of the US. These are correlated with 13 units in northwest Europe. There is a nearly complete succession in trans-Pecos Texas through the upper Albian to the upper part of the Turonian, but in central and northeast Texas there are major gaps. Twelve zones in the upper Albian-lower Cenomanian of central and northeast Texas can be correlated only approximately, and with difficulty, with nine zones or subzones in northwest Europe. The closest ammonite connections between North America and Europe were during the late Cenomanian. In contrast, during the earliest Cenomanian, there were very few elements in common between the two continents. -Authors
