Also known as DNMS
Where: Tamaulipas, Mexico (26.6° N, 99.5° W: paleocoordinates 26.6° N, 99.5° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: La Boca Formation (Huizachal Group), Pliensbachian (190.8 - 182.7 Ma)
• lower part of the La Boca Formation; originally dated as Middle Jurassic, but U-Pb isotopic data from zircon in a volcaniclastic rock from the lowest part of the formation yields an age of 189 plus/minus 0.2 Ma. The fossil-bearing sedimentary rocks are above this unit and conformable with it (see Montellano et al. 2008: JVP 28: 1130–1143).
• group of beds-level stratigraphic resolution
Environment/lithology: "floodplain"; lithology not reported
Size classes: macrofossils, mesofossils
Collection methods: IGM: Instituto de Geologia, Universidad Nacional Autonoma de Mexico, Ciudad Universitaria, Mexico
