New taxa among a remarkably diverse assemblage of fossil squamates from the Aguja Formation (lower Campanian) of West Texas

Supplemental Material: Stratigraphy and depositional history of the Aguja Formation (Upper Cretaceous, Campanian) of West Texas, southwestern USA

“…Vertebrate fossils rarely occur in the lower and upper parts of this member, and so it is unclear whether these may represent faunas distinct from that found in the middle of the unit. The "Lowerverse local fauna" (University of Texas Vertebrate Paleontology Laboratory TxVP 45947) occurs within this zone; it consists of a diverse assemblage of small terrestrial and aquatic vertebrates, including a variety of fishes (Wick, 2021b;Wick and Brink, 2022), amphibians (Wick, 2020(Wick, , 2021a, lizards (Wick and Shiller, 2020), small theropods and birds , and mammals (Brink, 2016). Lehman et al (2019) reviewed the larger vertebrate fauna including turtles, crocodylians, and dinosaurs known from all localities other than the Lowerverse site.…”

Paleontological inventory of Paleozoic, Late Mesozoic, and Cenozoic plant, invertebrate, and vertebrate fossil species from Big Bend National Park, Texas, USA - over a century of paleontological discovery

“…(including several new species) and contributed immeasurably to our understanding of Late Cretaceous terrestrial ecosystem of southern North America (e.g., Standhardt 1986;Rowe et al 1992;Sankey 2008Sankey , 2010Nydam et al 2013;Wick and Shiller 2020;Wick 2021a, b, c). Another significant circumstance is that BIBE sits apart geographically from other regions in North America that have produced fossils of similar age and type (e.g., Late Cretaceous vertebrate fossil-bearing locations in northern Mexico, New Mexico, Montana, and southern Canada among others).…”
