Macambira (Jurassic to of Brazil)

Where: Pernambuco, Brazil (8.6° S, 37.5° W: paleocoordinates 3.4° S, 5.1° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Capianga Member (Aliança Formation), Middle Jurassic to Middle Jurassic (174.7 - 145.0 Ma)

• "corresponds to the local RT-001 biozone, Dom João Stage of the Recôncavo Basin"

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; mudstone

• The presence of evaporites, chert and ephemeral fluvial systems are features very common in playa lake systems such as the Aliança Formation at Recôncavo Basin (Scherer et al., 2007) and Jatobá Basin (Fambrini et al., 2016), and the correlative Brejo Santo Formation in Araripe Basin (Fambrini et al., 2013). According to Guzmán-González et al. (2020) the playa lake of the Capianga Member presents a stable hydrology with a positive balance between precipitation and evaporation.
• consisting of red, purple to maroon, silty micaceous shale and mudstone with scattered green spots. Thin white sandy or carbonated layers are repeated cyclically throughout the section. Near the base, lenses of light-gray arkosic sandstone, shale, and laminae of gypsum and anhydrite are present. Thin-bedded dense limestone and chert are also found.

Size classes: macrofossils, mesofossils, microfossils
