We appreciate this opportunity for further discussion of the Brazos, Texas, K{\textendash}T boundary sequences and their timing with respect to the Chicxulub impact. Keller et al. (2007) used a multidisciplinary approach to document the stratigraphy, paleontology, mineralogy and geochemistry of the newly drilled Mullinax-1 core and a new outcrop sequence. Based on this multi-proxy dataset very strong evidence was presented that reveals that the Chicxulub impact predates the K{\textendash}T mass extinction (Keller et al., 2007). Schulte et al. take issue with this approach and our findings largely because they believe that the Chicxulub impact caused the K{\textendash}T mass extinction and therefore the K{\textendash}T boundary must be placed at the impact spherule layer (Schulte et al., 2008-this volume; Schulte et al., 2006; Smit et al., 1996).We welcome this opportunity to clarify misunderstandings, misconceptions and misinterpretations of the K{\textendash}T record in Texas and elsewhere.\ PDF
