#Efeméride La geóloga Florence Bascom (1862-1945) nació un 14 de julio.
Fue experta en cristalografía, mineralogía y petrografía.
Demostró petrográficamente que rocas consideradas sedimentarias eran en realidad flujos de lava metamorfizados.

I’m excited to share our new paper, out now in @PNASNews. We used #fossil #shark scales (denticles) preserved in coral reef sediments to reconstruct the pre-exploitation baseline of a reef shark community in Caribbean Panama. https://t.co/Sbl0sOm0J2 @odealab @mccauley_lab (1/18)
Sable shaping up beautifully. There's much to love, but I think I have a fav: look at the vivid bands of sandstone! Sediment rings of deep time. Sable has everything to do with layers of history, archaeology & strata. The crushed temporal ribbons are a fantastic symbol of that.
Hibernaspis
An armored jawless fish that looked similar to a guitar pick ,the serrated edges of its shield are the main way of telling apart the two known species
ALT: its believed that it would bury itself under the sediment of lagoons, possibly to avoid predators
The 1959 discovery of the OH 5 #hominin skull led to the first K-Ar age determination of sediments at Olduvai by Garniss Curtiss. Finding them to be 1.75 Ma—triple the expected age—he wrote: "One thing is certain. Olduvai Man is old, old, old!" #paleoanthropology #FossilFriday

@wukaimi @GeologischeBA "Geologische Übersichtskarte der Österreichisch-Ungarischen Monarchie" (1867-1871), first map including quaternary sediments, like ice-age windblown dust Löss
#FossilFriday The Zeeland Ridge Neanderthal was discovered in sediments extracted from the bottom of the North Sea. This is the first Pleistocene fossil hominin found under seawater. The partial frontal bone shows a lesion caused by an epidermoid cyst.

Day 2 #AncientBio21 showcase featuring ancient microbes and sediment DNA
Announcing a new issue always brings a warm feeling, and this one is full of imaginaries, life, resources, hidden infrastructures, sedimented histories, buried architectures, critical and contested sites ☄️ it’s the @ArchReview Underground issue https://t.co/6si0Vddf55
Here is a variant where sediment is kicked up by the Sorbinicharax. #MosasaurWeek #fish #sciart #paleoart #illustration #digital #art #wildlife
Morturneria, an antarctic Aristonectine, sucks up krill resting on the bottom of some sea ice. Morturneria was a supremely weird filter feeder, sifting through sediment to feast on small invertebrates
Megarachne
A mid sized eurypterid, it fed by raking trough riverbed floors looking for small hidden prey hiding in sediment
alt: its original specimen was confused as giant spider due to it being incomplete, ironically its one of the most complete specimens of its era
Fossil #hominin remains are often distorted when we find them, by natural weathering, moisture, or the weight of sediments that build above them. Sterkfontein, South Africa, has a complex array of depositional environments that left their mark on the fossils. #paleoanthropology
@MPennanti They didn't had idea... HOW FAST I AM, BOIIIIIIIIIIIIIIII! And you must be wondering: "Wait, Where's Sedimentary?"
In the deep sea the crushing pressures had created this being from sediment. It was the first time pure light had lit up this suffocating darkness.
Megalograptus
An early eurypterid recognized by the large spiky appendages, when originally discovered it was confused as ancient writing due to its long spikes
ALT:its unknown what the large spikes where used for, probably to rake trough sediment looking for hidden prey
@EJPointer @IrvingForbush2 @derosajoe51 @RJDownard @TTDerandere @erb_kay A middle Cambrian formation just above (after) the Wheeler and just below (before) the Weeks.
Layers of ocean bottom sediment being laid down around a continent near the equator 520 million years ago. Today that same continent has rotated 90 degrees and moved north.
