Collection methods and comments
Collection excludes: | some genera,some macrofossils,species names | ||
Collection methods: | selective quarrying,mechanical,field collection | ||
Reason for describing collection: | taxonomic analysis | ||
Museum repositories: | FMNH | ||
Collectors: | D. Krause & crews | Collection dates: | 1993, 1995, 1997, 1999, 2001, 2004, 2007 |
Collection method comments: Faunal list from formation includes "fishes, frogs, turtles, snakes, lizards, crocodiles, sauropod and non-avian theropod dinosaurs, and mammals", but these are certainly not all from site MAD 93-18. The site is productive and does contain many other taxa, but these were collected at other times, and are not listed in this paper - other papers need to be consulted. |
