Sanlimiao (Cretaceous of China)

Also known as Xixia Basin

Where: Henan, China (33.3° N, 111.5° E: paleocoordinates 32.5° N, 103.8° E)

• coordinate based on nearby landmark

• hand sample-level geographic resolution

When: Majiacun Formation, Middle Santonian (85.8 - 83.5 Ma)

• "The bed from which the fossil was recovered is in the mid-section of the formation, so although the formation spans the Late Coniacian through to the Late Santonian...the tooth is likely from the Middle Santonian"

Environment/lithology: terrestrial; siltstone and calcareous sandstone

• "The tooth bearing beds are a set of light purple and red muddy siltstones and fine calcareous sandstone."

Size class: macrofossils

• XMDFEC V0010 and casts IVPP FV* 1786

Collection methods: Xixia Museum of Dinosaur Fossil Eggs of China collection
