The Paluxy River Controversy centers on the identification of certain Ichnofossils (that is, Trace Fossils) which for more than 50 years have been reported to accompany dinosaurian foot prints in the dolomite beds of the Lower Glen Rose Formation, near Forth Worth, Texas. The formation has been assigned an approximate age of 100 million years, according to its position in the Chronostratigraphic Geologic Column. The dolomite beds are separated by clay beds, making it an Ideal lithological sequence for the preservation of footprints.
