Late Ordovician and early Silurian virgianid and stricklandioid brachiopods from North Greenland: implications for a warm‐water faunal province

open access: yesPapers in Palaeontology, Volume 10, Issue 1, January/February 2024.
Abstract An unusually rich and diverse suite of virgianid brachiopods, hitherto poorly known, is systematically described here for the first time from the Ordovician–Silurian boundary interval (late Katian – Aeronian) of North Greenland. The Late Ordovician virgianids comprise typical taxa of the warm‐water Tcherskidium fauna (e.g.

Ludlow (Silurian) stromatoporoid biostromes from Gotland, Sweden: facies, depositional models and modern analogues

open access: yes, 2002
Stacked stromatoporoid-dominated biostromes of the Ludlow-age Hemse Group (Silurian) in eastern Gotland, Sweden, are 0.5-5 m thick and a few tens of metres to >1 km in lateral extent.

Contrasting morphology and growth habits of Frutexites in Late Devonian reef complexes of the Canning Basin, northwestern Australia

open access: yesGeobiology, Volume 22, Issue 1, January/February 2024.
Abstract Frutexites‐like microstructures are described from the exhumed Late Devonian reef complexes of the northern Canning Basin, Western Australia. Several high‐resolution imaging techniques, including X‐ray microcomputerised tomography, scanning electron microscopy and X‐ray fluorescence microscopy, were used to investigate morphology and ...

On the Structure of the Stromatoporoid Skeleton, and on Eozoon [PDF]

open access: yesNature, 1912
I HAVE pointed out (Annals. Mag. Nat. Hist., September, 1912) that Stromatoporoids are Foraminifera, but I did not give an explanation of the structure of the skeleton. I now find that the clue to this structure lies in the “astrorhizae” or stellate patterns on the surface of many of these fossils.

Very large stromatoporoid indicating Early Frasnian reef core (Holy Cross Mts., Poland) [PDF]

open access: yes, 2004
A large stromatoporoid Actinostroma cf. crassepilatum Lecompte, 1951, at least 8.5 m in diameter and 0.85 m in height, occurs in the Śluchowice quarry in Kielce, Holy Cross Mountains.

Cambrian, Ordovician and Silurian non-stromatoporoid Porifera [PDF]

open access: yes, 2013
The Cambrian, Ordovician and Silurian distributions of non-stromatoporoid sponges are reviewed. The earliest Cambrian faunas contain mostly hexactinellids, with protomonaxonids dominating middle Cambrian assemblages.

Devonian stromatoporoid fauna of the Bent Horn oilfield, Cameron Island, Northwest Territories

open access: yes, 1998
The reservoir reef carbonates at the Bent Horn field have been referred to as the Blue Fiord Formation, but they are younger than the type Blue Fiord of Ellesmere Island. The top of these carbonates, from which the stromatoporoid fauna is here described,
