...Sarah E. Gabbott; Claire Browning; Johannes N. Theron; Rowan J. Whittle Abstract Fossils of the Late Ordovician Soom Shale Lagerstätte are characterized by exceptional preservation of their soft tissues in clay minerals. The low-diversity community lived in an unusual cold-water setting, dominated...

...ROWAN WHITTLE; SARAH GABBOTT; RICHARD ALDRIDGE; JOHANNES THERON Abstract More than 20 partial scolecodont clusters were recovered from the Soom Shale Lagerstätte, South Africa. The specimens were found in association with chitinozoans, algae, conodont apparatuses and the enigmatic needle-like...

...SARAH E. GABBOTT; RICHARD J. ALDRIDGE; JOHANNES N. THERON Abstract The Upper Ordovician (Ashgill) Soom Shale lagerstätte preserves chitinozoans on the bedding planes as scattered individuals and, more significantly, in linked chains, in aggregated masses and associated with organic envelopes...

... Shale Lagerstätte. Correlation of the Soom Shale chitinozoans with identical assemblages in post-glacial, transgressive deposits of Northern Africa is possible; both faunas occur in shales that overlie glacial diamictites of the Hirnantian glaciation. A new species, Spinachitina verniersi n. sp...

... Society, 2001 2001 The Soom Shale, lower member of the Upper Ordovician Cedarberg Formation, is a prominent argillaceous unit within the Cambrian-Devonian Table Mountain Group of South Africa ( Theron et al. 1990 ). The Soom Shale is a conservation-lagerstâtte preserving the soft tissues...

.... apparatuses from the Winneshiek Lagerstätte have an estimated average length of 2–3 cm, which is larger than the Upper Ordovician apparatuses described from the Soom Shale in South Africa (e.g., Theron et al., 1990 ; Aldridge et al., 2013 ). Although individual elements from both...
