Non-calcifying #algae are rare in the #fossilrecord, requiring unusual conditions for preservation. This is Winnipegia cuneata, a probable onchrophyte #alga from the Late #Ordovician (~450 MYA) Cat Head Mbr, Red River Fm - Cat Head-McBeth Point #Lagerstatte, Lake Winnipeg, #Manitoba 🇨🇦 #FossilFriday
A small trapezoid-shaped slab of pale buff dolostone bearing several clusters of contrasting rust-coloured tapered fronds, radiating from short "stems".

In the face of gut-churning events everywhere, I turn again to the pre-human #fossilrecord for a moment of peace. This is Cyrenopsis meeki, a #bivalve #mollusc showing precious opal replacement of original shell material. Early #Cretaceous (~118 MYA), Coober Pedy, #SouthAustralia #MolluscMonday
A small fossil bivalve mollusc, measuring about 2.5 cm in width, is seen from the left side. It has been slightly polished to reveal a fresh surface of precious opal, which replaced the original aragonitic shell material and internal cast subsequent to initial fossilization. The typical opal iridescent "play-of-colour" can be seen in small patches of blue, green, and orange. Specimen catalogued in the Invertebrate Palaeontology collections of the Royal Ontario Museum.

2/ Fossil records show Megalodon teeth date back 23 million to 2.6 million years ago. No teeth found in younger strata. Suggests Megalodon went extinct around 2.6 million years ago. #ExtinctionEvidence #FossilRecord

4- The pycnogonid crown group (=Pantopoda) preceeds the appearance of the first pantopod fossil by ~206.5 Ma. Why this hole in the fossil record? Sea spiders have fragile, low-fossilization bodies and likely lived in environments unsuitable for fossil preservation. #FossilRecord #Paleontology

Current events call for a "don't let the bastards grind you down" kind of post. These #Ordovician #bryozoans, #brachiopods & #gastropods entered the #fossilrecord ~450 MYA only to be scoured by a Pleistocene glacier. Be like these #fossils - endure! Verulam Fm, Ramara Tp, #Ontario 🇨🇦 #FossilFriday
A small, irregularly shaped slab of limestone is being held by hand in the raking sunlight. The flat surface, stained pale orange by iron minerals, shows a series of straight parallel grooves or scratches -- these are glacial striations cut by the passage of abrasive rock fragments and mineral grains embedded in the sole of the glacier. Numerous fossil fragments are seen on the slab surface. Some of these have been ground through at various angles and show as complete or partial cross sections. Other fragments (lower left and far right) have escaped glacial sectioning and still stand in relief. Close up of the glacially polished slab surface showing several medium- and high-spired gastropods in section, as well as the outlines of rhynchonellid brachiopods. More of the same surface with sections through trepostome bryozoans and a planispiral gastropod.

Horses evolved right here in the Americas, long before anyone tamed them.
