Some notes on a variability of Bothriolepidids (Placodermi, Antiarchi): unusual specimen of Livnolepis Heckeri (Luksevics) from the famennian of Tver region, European Russia

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2019
The fragment of the skull cap of placoderm Livnolepis heckeri (Luksevics) from the Bilovo Formation (Famennian, Upper Devonian) near the Bilovo Village of Tver Region has been described.

Analyses on Prestress Loss and Flexural Performance of the Laminated Bamboo Beam Applied with Prestressed BFRP Sheet

open access: yesAdvances in Civil Engineering, Volume 2019, Issue 1, 2019., 2019
Inspired by the studies about wooden beam applied with prestressed steel plate and bamboo beam strengthened by fiber‐reinforced polymer (FRP), this paper aims to explore the applicability of the prestressed basalt fiber‐reinforced polymer (BFRP) sheet to the laminated bamboo beam and the variation of the flexural performance of the laminated bamboo ...

Russia-UK collaboration in paleontology: past, present, and future [PDF]

open access: yes, 2017
There is a long history of collaboration between Russia and the United Kingdom in paleontology. This began, arguably, in 1821, with the seminal work by William Fox-Strangways, who produced a geological map of the area around St Petersburg. Most famously,

An Experimental Investigation on Flexural Behavior of Reinforced Concrete Beams Strengthened by an Intelligent CFRP Plate with Built‐In Optical Fiber Bragg Grating Sensors

open access: yesJournal of Sensors, Volume 2018, Issue 1, 2018., 2018
The difficulties induced from high‐durability package, large‐scale measurement, and sensor installation make it a big challenge but an urgent need to predict the mechanical behavior of strengthened reinforced concrete structure with the externally bonded fiber‐reinforced polymer (FRP) plate under harsh environments and rough construction process. In an

Late Devonian antiarch remains (placoderm fish) from the Gilberton Formation, north Queensland

open access: yesMemoirs of the Queensland Museum - Nature, 2020
New Devonian fish remains are described from the lower part of the Gilberton Formation of north Queensland, the first identifiable specimens found since the original specimen was described in 1936. They include the first determinable dermal skull bones from this deposit.

CT investigations of Australian Devonian fossil fishes, and the application of 3D segmentation and modelling in vertebrate morphology [PDF]

open access: yes, 2021
This thesis by compilation covers four publications, which together demonstrate and apply computed tomography (CT) data, three-dimensional (3D) segmentation, and 3D printing, for the non-destructive high-resolution detection of internal structure in ...

Sarcopterygian and other Fishes from the Marine Upper Devonian of Colorado, U.S.A. [PDF]

open access: yes, 2010
The fish fauna of Upper Devonian deposits of SW Colorado is described and compared with those of Central Colorado. The osteolepidid Litoptychus is redescribed including skull roof, cheek, palatoquadrate, cleithrum and postcranial elements.

Lungfish‐like antero‐labial tooth addition and amphibian‐like enameloid‐enamel transition in the coronoid of a Devonian stem actinopterygian

open access: yesJournal of Anatomy, Volume 247, Issue 3-4, Page 418-441, September/October 2025.
The tooth patterning logic, which cannot be inferred from surface morphology, is revealed by visualizing buried tooth remnants in 3D. The primary teeth are added labially, initially organized in radial rows, which transition into linear rows where the coronoid becomes slender.
