Placidichthys-type locality (Cretaceous of Brazil)

Where: Ceará, Brazil (7.2° S, 40.0° W: paleocoordinates 12.2° S, 11.4° W)

• coordinate based on nearby landmark

When: Romualdo Member (Santana Formation), Albian (112.6 - 99.7 Ma)

• Romualdo Member, Santana Formation, Lower Cretaceous, Albian

• member-level stratigraphic resolution

Environment/lithology: marine; nodular lithology not reported

Size class: macrofossils

Collection methods: In 1995 the late Professor Murilo R. Lima gave me an enigmatic and badly preserved fossil nodule from the Santana Formation...The recent discovery of new, better-preserved specimens in the nodules of the Santana Formation and in the Crato Formation, as well as the preparation of two specimens using chemical techniques, allows the description of this new halecomorph.
