"Fossils reveal ‘latitudinal traps’ that increased the risk of extinction for marine species"
tl;dr: over the last 540 million years, species living along north-south oriented coastlines were less likely to become extinct than those living along east-west oriented coastlines.

Messinian salinity crisis (Paleogeography 🦕)
The Messinian salinity crisis was an event in which the Mediterranean Sea went into a cycle of partial or nearly complete desiccation throughout the latter part of the Messinian age of the Miocene epoch, from 5.96 to 5.33 Ma. It ended with the […]

Lake Agassiz (Paleogeography 🦕)
Lake Agassiz was a large proglacial lake that existed in central North America during the late Pleistocene, fed by meltwater from the retreating Laurentide Ice Sheet at the end of the last glacial period. At its peak, the lake's area was larger than all of the […]
Proglacial lakes of Minnesota (Paleogeography 🦕)
The proglacial lakes of Minnesota were lakes created in what is now the U.S. state of Minnesota in central North America in the waning years of the last glacial period. As the Laurentide Ice Sheet decayed at the end of the Wisconsin glaciation […]
Betic corridor (Paleogeography 🦕)
The Betic Corridor, or North-Betic Strait, was a strait of water connecting the Mediterranean Sea with the Atlantic Ocean that once separated the Iberian plate from the Eurasian Plate through the Betic Cordillera. Its closure approximately 5.96 million years […]
Marine Isotope Stage 13 (Paleogeography 🦕)
Marine Isotope Stage 13 or MIS 13 is a Marine isotope stage in the geologic temperature record, in Britain covering the Cromerian interglacial period between ~524,000 and 474,000 years ago. It is split into three substages, MIS 13a MIS 13b, and MIS 13c […]
Paleolimnology (Paleogeography 🦕)
Paleolimnology is a scientific sub-discipline closely related to both limnology and paleoecology. Paleolimnological studies focus on reconstructing the past environments of inland waters using the geologic record, especially […]

Stratotype (Paleogeography 🦕)
In geology, a stratotype or type section is the physical location or outcrop of a particular reference exposure of a stratigraphic sequence or stratigraphic boundary. If the stratigraphic unit is layered, it is called a […]

Ancient coastlines may hold the key to how humans first left Africa. New reconstructions reveal submerged migration routes across the Red Sea, Sinai, and Foul Bay. #HumanEvolution #Archaeology #Paleogeography #OutOfAfrica #Aquaterra
thanks to maps like this I often want to think of South America and Africa as "North Gondwanaland" but actually apparently they are "West Gondwanaland"?

Palaeogeography (Paleogeography 🦕)
Palaeogeography is the study of historical geography, generally physical landscapes. Palaeogeography can also include the study of human or cultural environments. When the focus is specifically on landforms, the term […]

Erathem (Geology terminology ⛰️)
In stratigraphy, paleontology, geology, and geobiology, an erathem is the total stratigraphic unit deposited during a certain corresponding span of time during an era in the geologic timescale. It can therefore be used as a chronostratigraphic unit of time which […]

Stage (stratigraphy) (Geology terminology ⛰️)
In chronostratigraphy, a stage is a succession of rock strata laid down in a single age on the geologic timescale, which usually represents millions of years of deposition. A given stage of rock and the corresponding age of time will by convention […]

Danube fan (Paleogeography 🦕)
The Danube fan is a relict sedimentary feature in the northwestern part of the bottom of the Black Sea. It crosses three of its four major physiographic provinces: basin slope, basin apron, and the Euxine abyssal plain) and splits the abyssal plain into two […]
Great Tehuelche Paleolake (Paleogeography 🦕)
The Paleolake Tehuelche is the name for several former lakes that existed in the area of Torres del Paine in southern Patagonia. These were proglacial lakes that existed next to the Patagonian Ice Sheet during the Late Pleistocene and Early […]
Lake Souris (Paleogeography 🦕)
The Glacial Lake Souris occupied the basin of the Souris River from the most southern portion of this river's loop in North Dakota to its elbow in Manitoba, where it turned sharply northward and passed through the Tiger Hills […]

Urstrom (Paleogeography 🦕)
The Urstrom is a geologists' name for a great glacial age river of the Polish and north German plain, which drained the combined melt-waters from the northern headwaters of the Alps and the southern part of the Scandinavian ice during the Devensian ice age […]
