Cuidad Victoria, USNM 13002 (Silurian to of Mexico)

Where: Tamaulipas, Mexico (23.8° N, 99.3° W: paleocoordinates 25.6° S, 76.0° W)

• small collection-level geographic resolution

When: Santa Ana Limestone Member (Canon de Caballeros Formation), Homerian to Homerian (430.5 - 425.6 Ma)

• The authors indicate that the Santa Ana Member may be diachronous, as to the N some taxa there indicate an age of late Llandovery. They feel that it isn't diachronous, just the age determination needs more work.

• member-level stratigraphic resolution

Environment/lithology: sand shoal; lithified, shelly/skeletal grainstone

• "The fauna from the Santa Ana at loc. JS93-88 represents a rough water Pentamerus community assigned to BA3. Dominance of Atrypa in Stinnesbeck collection...indicates a discrete ecological setting although BA3 is likewise indicated."
• distinctive bioclastic grainstone commonly with abundant coarse grains and granules of polycrystalline and monocrystalline quartz.
