“…Farther south, the Cenomanian‐Turonian Eagle Ford Shale of Texas is probably the best studied OAE2 interval in the Gulf of Mexico region (Corbett & Watkins, ; Corbett, Watkins, & Popspichal, ; Denne and Breyer, ; Denne et al, , ; Dodsworth, ; Donovan et al, ; Eldrett, Minisini, & Bergman, ; Eldrett et al, ; Frush & Eicher, ; Lowery & Leckie, ; Lowery et al, ; Lundquist, ; Pessagno, ; Phelps et al, ). Like in the Western Interior, the pre‐OAE2 sedimentary rocks of Texas are enriched in total organic carbon (TOC) up to ~9 wt % (Hentz & Ruppel, ) and contain proxy evidence for seafloor anoxia, including a lack of benthic foraminifera, absence of bioturbation, and enrichment in certain redox sensitive trace metals (e.g., Denne et al, ; Denne & Breyer, ; Donovan et al, ; Eldrett et al, , ; Lowery et al, ).…”
