| Zusammenfassung |
| We present evidence for methane seepage during the Early Jurassic (185 Ma) in the form of
newly discovered extensive occurrences of carbonate concretions that resemble the
subsurface plumbing system of better known Cenozoic to Recent examples of cold seep
carbonates. Columnar carbonate concretions of up to 1 m in length that are perpendicular to
bedding, occur abundantly in the Upper Pliensbachian (upper Amaltheus margaritatus
Zone, gibbosus Subzone) in outcrops in the vicinity of Rivi |
