The bivalve Cuneamya from the Late Ordovician of Bohemia [PDF]
Fossil Imprint, 2019 Abstract The bivalve species Cuneamya catilloides from the Late Ordovician of Bohemia, previously assigned to the genus Grammysia, is revised. Cuneamya catilloides is an important element of the Modiolopsis Community Group in the Letná Formation. The genus Grammysia very probably does not occur in the Ordovician of Bohemia and is restricted to the ...

Rapid recovery from the Late Ordovician mass extinction [PDF]
Proceedings of the National Academy of Sciences, 2004 Understanding the evolutionary role of mass extinctions requires detailed knowledge of postextinction recoveries. However, most models of recovery hinge on a direct reading of the fossil record, and several recent studies have suggested that the fossil record is especially incomplete for recovery intervals immediately after mass extinctions.

The position of graptolites within Lower Palaeozoic planktic ecosystems. [PDF]
, 1993 An integrated approach has been used to assess the palaeoecology of graptolites both as a discrete group and also as a part of the biota present within Ordovician and Silurian planktic realms.

The appearance of Rosenella (stromatoporoid sponge) in Baltica: new species from the Pirgu Stage (Katian, Upper Ordovician) of Estonia [PDF]
Estonian Journal of Earth SciencesThe Katian Age, part of the Late Ordovician Epoch, was a period of significant stromatoporoid diversification. However, their fossil record is often less continuous, hindering our understanding of their diversity and diversification.

Deep Underground Science and Engineering, EarlyView.The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

Fish Scales: A Multifunctional Biomaterial from Nature
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...
