Devonian reef-builders are entirely extinct in the modern day: Stromatoporoids died out in the end-Devonian Hangenberg event, while rugose and tabulate corals went extinct at the Permian-Triassic extinction.
23 sty 2021 · The Devonian extinction ushered in not only the land-bound tetrapods, but also the animals that command the marine vertebrate world to this day: ray-finned (or bony) fish, and cartilaginous fish, like sharks, rays and chimeras.
11 paź 2024 · Particularly in the Late Devonian, extinction events may relate to periods of abrupt cooling associated with the development of glaciers and the substantial lowering of sea level. It has been argued that patterns of faunal change at the Kellwasser Event are consistent with global cooling.
There are three important extinctions in latter half of the Devonian Period, each separated by about 10 million years. Only one of these, at the end of a time interval called the Frasnian, is normally considered large enough to be one of the “Big Five.”
27 kwi 2021 · Early lobe-finned fishes and tetrapod (four-limbed) vertebrates were severely impacted by the Late Devonian mass extinction. The destruction of Devonian-style metazoan reefs triggered a permanent change in global marine ecosystems.
21 gru 2021 · Here, we investigate how different types of risk intersect in the well-preserved brachiopod fauna of the Appalachian Foreland Basin during the two pulses of the Frasnian–Famennian mass ...
The role of invasive species during the Late Devonian Biodiversity Crisis has been characterized using a series of GIS, phylogenetic, biodiversity, and paleoecological analyses.
