A new insect boring in fossil wood from the Iranian Upper Cretaceous
Palaeontology, Volume 68, Issue 5, September/October 2025.Abstract Here we describe Iranichnus farsensis igen. et isp. nov., a bioerosion trace in fossil wood characterized by a system of sinuous channels in the wood under the bark, also bearing small borings radially oriented within the channels. We attributed this to insects, most probably a beetle from one of the groups known to feed on wood just under the

Sedimentology, Volume 72, Issue 5, Page 1518-1547, August 2025.ABSTRACT Recent interest in Mg‐rich silicate formation stems from its role as a valuable palaeoclimatic indicator in fluvio‐lacustrine environments and its insights into metal geochemical cycling. Traditionally, Mg‐silicate genesis in lacustrine contexts is linked to alkaline or saline conditions in closed, evaporitic basins.

Gangliogenesis in the Prosobranch Gastropod Ilyanassa obsoleta [PDF]
, 1996 We determined that the larval nervous system of Ilyanassa obsoleta contains paired cerebral, pleural, pedal, buccal, and intestinal ganglia and unpaired apical, osphradial, and visceral ganglia.

Beiträge zur Torsion und Frühevolution der Gastropoden
, 2009 Contributions to torsion and early evolution of the gastropods The phylogenetical model, which is presented here, is directed by trying to explain torsion of gastropods out of biomechanical conditions.

Macrofaunal contributions to benthic nutrient fluxes revealed by radium disequilibrium
Limnology and Oceanography, Volume 70, Issue 5, Page 1345-1358, May 2025.Abstract The benthic flux of nutrients underpins marine food webs, influences conditions for life in the oceans, and contributes to climatic feedback. Estimates of these fluxes' contributions to macro‐ and micronutrient cycles are, however, highly variable, generating significant uncertainty in biogeochemical models.

Die Torsion der Gastropoda ‐ ein biomechanischer Prozeß
, 2009 The recently proposed biomechanical model of gastropod torsion (edlinger 1988 a, b) is rejected on various reasons. First, the assumed original conditions in Polyplacophora and Tryblidiida as well as the constructed original condition in the Gastropoda ...

Larval Shell Muscles in the Abalone Haliotis kamtschatkana.
The Biological Bulletin, 1997 I used light and electron microscopy to investigate shell-attached muscles in larvae of Haliotis kamtschatkana Jonas, 1845, because an early description of these muscles in H.

The Depositional Record, Volume 11, Issue 2, Page 616-636, April 2025.While the Smithian–Spathian boundary carbon isotopic excursion has been traditionally interpreted as capturing global carbon cycle behaviour, recent studies have suggested that at least some Early Triassic carbon isotopic excursions may incorporate influences from authigenic or early diagenetic processes.

Marine molluscan diversity in India – exploitation, conservation [PDF]
, 2017 The molluscs (soft bodied animals) belong to the large and diverse phylum Mollusca, which includes a variety of familiar animals well-known as decorative shells or as seafood. These range from tiny snails, clams, and abalone to larger organisms such as
