Estheriahaugen North (Devonian of Svalbard and Jan Mayen)

Where: Spitsbergen, Svalbard and Jan Mayen (78.7° N, 16.2° E: paleocoordinates 1.6° N, 7.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Fiskekløfta Member (Tordalen Formation), Givetian (387.7 - 382.7 Ma)

• Fiskekløfta Unit 6 per Vogt 1941

Environment/lithology: marine; nodular ironstone and black, brown mudstone

• "Newman et al. (2020) considered the environment of deposition to be a backwater marine environment, most likely a lagoon. Certainly, there is a marine influence, although a lack of marine invertebrate species may indicate that the probable lagoon was part of an estuarine complex." (Newman et al 2021)
• "Fossils [...] are mostly preserved in ironstone nodules found in a 30 metre-thick, poorly stratified, brownish-black mudstone" (Newman et al 2021)

Size class: macrofossils

Preservation: concretion

Collected by M. J. Newman, R. Jones, P. Gavin, R. Gavin, T. Tuuling, J. Armstrong, C. Moore, A. Moore, S. Waters in 2018
