Cruziana traces from the Late Silurian (Pridoli) carbonate shelf of Saaremaa, Estonia
Late Pridoli Cruziana traces have recently been found in carbonate shelf sediments of the Ohesaare Formation on Saaremaa Island, Estonia. Cruziana isp. is interpreted here as a locomotory trace (repichnia) of an arthropod, possibly a trilobite. Cruziana traces previously known from the Silurian of Baltica differ from Cruziana isp., indicating that the diversity of Cruziana traces in the late Silurian of Baltica was higher than previously thought
In Service to the Narrative: \u3ci\u3eThe Buried Giant\u3c/i\u3e Through a Folklore Lens
Kazuo Ishiguro’s 2016 novel The Buried Giant has a history of causing contention over how it should be read. Literature, fiction, fantasy, historical fantasy, and other forms have all be the jumping off point for many analysts, but this paper argues that perhaps the best way to read this work is as an analysis of Western literary canon and violence through the lens of oral folklore. Using Axel Olrik’s Epic Laws of Folk Narrative or sagenwelt offers insights into how the novel functions as an examination of characters bound up in predestined narratives due to the nature of their original historical context, and further deconstructs those narratives to prove points about personal agency and cyclical violence

Cornulitid epibionts on brachiopod shells from the Late Ordovician (middle Ashgill) of East China
This is the first record of Cornulites sp. as an epibiont on brachiopods from the middle Ashgill, Late Ordovician, of the South China Palaeoplate. Twenty-one cornulitid specimens were found attached to the brachiopod shells of Altaethyrella zhejiangensis and Ovalospira dichotoma. Both the location of cornulitids and their orientation on the brachiopod shells indicate a possible commensal relationship between the cornulitids and their hosts
New late ordovician cornulitids from peru
Two new species of cornulitids, Cornulites zatoni sp. nov. and Cornulites vilcae sp. nov., are described from the lower part (Sandbian) of the Calapuja Formation of south-western Peru. Late Ordovician cornulitid diversities of Peru (Gondwana) and Estonia (Baltica) are similar. Aggregative growth form dominates among the cornulitids of the Sandbian of Peru. Multiple oriented C. zatoni sp. nov. specimens on a strophomenid brachiopod likely represent a syn vivo encrustation. Cornulitids from the Sandbian of Peru differ from those known from the Sandbian of Baltica. C. zatoni sp. nov. possibly also occurs in the Late Ordovician of Laurentia. © 2016, Czech Geological Survey. All rights reserved.Peer reviewe
A new species of Conchicolites (Cornulitida, Tentaculita) from the Wenlock of Gotland, Sweden
A new cornulitid species, Conchicolites crispisulcans sp. nov., is described from the Wenlock of Gotland, Sweden. The undulating edge of C. crispisulcans sp. nov. peristomes is unique among the species of Conchicolites. This undulating peristome edge may reflect the position of setae at the tube aperture. The presence of the undulating peristome edge supports the hypothesis that cornulitids had setae and were probably related to brachiopods
Ichnofossiles associés à des coquilles de lingulides du Permien inférieur du Brésil.
Lingulides from Lower Permian of Brazil (24% substrates) showed signs of bioerosion in
form of multiple small shallow pits that resemble incomplete Oichnus paraboloides borings. A single
lingulide valve showed a centrally located large circular predatory Oichnus simplex boring. Several lingulide
shells (c. 21%) show small Arachnostega traces in their interior. The diameter of Arachnostega
burrows is relatively constant. These burrows are more similar to juvenile stages of Arachnostega
gastrochaena and do not form well-developed meshwork of tunnels. This is the first record of Arachnostega
from the interior of lingulide shells and indicates that even very small lingulide shells were suitable
substrates for cryptic organisms.Les lingulides du Permien inférieur du Brésil (24% des substrats) portent des traces de bio-érosion
sous forme de nombreux petits trous peu profonds qui ressemblent à des perforations incomplètes
d'Oichnus paraboloides. Une seule coquille de lingulide montre une grande perforation prédatrice circulaire
d'Oichnus simplex localisée en son centre. Plusieurs coquilles de lingulides (environ 21%) présentent
des traces d'Arachnostega à l'intérieur. Le diamètre des terriers d'Arachnostega est relativement
constant. Ces terriers sont très semblables aux stades juvéniles d'Arachnostega gastrochaena et ne
forment pas de réseaux de tunnels bien développés. C'est la première mention d'Arachnostega à l'intérieur
de coquilles de lingulides et ce qui prouve que des coquilles de lingulides, même très petites,
pouvaient constituer un substrat convenable pour des organismes cryptiques
Tube ultrastructure of <i>Pomatoceros americanus</i> (Polychaeta, Serpulidae): Implications for the tube formation of serpulids
A new microconchid species from the Silurian of Baltica
The diversity of Silurian microconchids is still poorly understood. Here, a new microconchid tubeworm species,
Palaeoconchus wilsoni, is described from the Silurian (Ludlow) encrusting rugose corals from Estonia (Saaremaa Island) and a brachiopod shell from Sweden (Gotland). In Estonia, the microconchids are a dominant constituent of the encrusting assemblages, associated with cornulitids, Anticalyptraea, auloporids, trepostome bryozoans, hederelloids and enigmatic ascodictyids. It is notable that these Silurian encrusting assemblages are clearly dominated by tentaculitoids (microconchids, cornulitids and Anticalyptraea) which very often co-exist on the same coral host. Morphologically similar microconchids and Anticalyptraea may have exploited a more similar ecological niche than the straight-shelled cornulitids. However, the clear predominance of microconchids over Anticalyptraea in the communities may indicate that this genus was a less effective competitor for food than microconchid tubeworms
