Ecology and Evolution, Volume 9, Issue 22, Page 12390-12407, November 2019., 2019 The mitogenomes of M. lauensis and M. verrilli show novel arrangements of mitochondrial genes. Comparisons of mitochondrial gene rearrangements, to some extent, are a useful tool for phylogenetic studies. Abstract Hydrothermal vents are considered as one of the most extremely harsh environments on the Earth.

Eocene belemnites from Hungary
Papers in Palaeontology, Volume 12, Issue 2, March/April 2026.Abstract The Middle Eocene nummulitic limestone at Dudar, Transdanubian Hungary, has yielded several belemnite rostra during the last 60–70 years. The correct interpretation of these fossils was made possible by the fact that one of these specimens retained the remnants of the conotheca within the alveolus, while others preserved the conical, tapering ...

Microstructural and geochemical evidence offers a solution to the cephalopod cameral deposits riddle
Palaeontology, Volume 68, Issue 6, November/December 2025.Abstract Orthoceratoid cephalopods are common in the Palaeozoic rock record but went extinct in the Late Triassic. Many orthoceratoids contain cameral deposits, which are enigmatic calcareous structures within their chambered shell that presumably balanced their straight conchs in a horizontal position. Since the mid‐19th century, palaeontologists have

Cephalopod classification and taxonomy [PDF]
, 2015 Chambered nautilus, cuttlefishes, squids and octopus are the four major groups of cephalopods, which belong to the highly evolved class of phylum Mollusca. Cephalopods are the third largest molluscan class after bivalves and gastropods and consist of

Non-invasive diagnostics in fossils - Magnetic Resonance Imaging of pathological belemnites [PDF]
, 2005 For more than a decade, Magnetic Resonance Imaging (MRI) has been routinely employed in clinical diagnostics because it allows non-invasive studies of anatomical structures and physiological processes in vivo and to differentiate between healthy and ...

Davidson Seamount Taxonomic Guide [PDF]
, 2008 Davidson Seamount is one of the largest seamounts in U.S. waters and the first to be characterized as a “seamount.” In 2002 and 2006, the Monterey Bay National Marine Sanctuary (MBNMS) led two multi-institutional expeditions to characterize the geology ...

Experimental taphonomy of artemia reveals the role of endogenous microbes in mediating decay and fossilization [PDF]
, 2015 Exceptionally preserved fossils provide major insights into the evolutionary history of life. Microbial activity is thought to play a pivotal role in both the decay of organisms and the preservation of soft tissue in the fossil record, though this has ...
