A gorgeous specimen for #FossilFriday : the internal cast of a Jurassic bivalve (Pleuromya cf. uniformis), turned into a talisman with a religious Islamic inscription : ‘There is no god but Allāh [and] Muḥammad is His Prophet’ #PaleoSky ⚒️🏺🧪🦑🦕
Fig. 1. Pleuromya cf. uniformis (Sowerby 1813), Jurassic, Morocco. Internal mould of articulated specimen bearing a religious inscription in high relief. Museo Geominero, Madrid, catalogue number MGM-7809X. (a) Left valve view; (b) right valve view; (c) anterior view; (d) dorsal view; and (e) detail showing striations visible on the surface of the letters (left arrow) and how a fissure in the rock also affects the letter (right arrows), indicating that the letters were carved in high relief and do not represent surface adherences of any foreign material. The thick patina of dirt that covered the specimen, originally dark grey in colour, was removed by washing with detergents, alternating with immersions in hydrogen peroxide.

$50.1 million could fund over 400 doctorates; 933 years worth of annual curator salaries (UK), or running cost for a millennium-worth of free events like the Lyme Regis Fossil Festival. It is inane that people can accumulate such wealth, and use it explicitly to cause public harm.

The entire scene is shown within the shape of a blue whale. Despite the vast gulf in form and time between the two animals, they are of the same group: Cetacea.

Historical #refugia formed due to these sea ice barriers where bowhead whales were shielded from the devastating impacts of whaling for decades. The two bowhead whale stocks currently recovering had the greatest amount of past refugia, suggesting those stocks were not depleted as severely. 4/🐋
Top-down map of the Arctic showing the spread of bowhead whaling throughout the Arctic. The map shows Europe, Greenland, Canada, Alaska, Siberia. The four bowhead whale stocks are shown in between these landmasses (clockwise from top-right: East Greenland-Svalbard-Barents stock; East Canada-West Greenland stock; Bering-Chukchi-Beaufort stock; Sea of Okhotsk stock).

The color gradient shows how many years after pelagic whaling began in one of the four bowhead whale stocks that a particular grid cell began to experience whaling. This delay was because hazardous Arctic sea ice made travel in these frigid conditions extremely challenging for whalers. 

Areas in darker colors (with a very delayed onset of whaling) functioned as historic refugia for bowhead whales. These areas included Prince Regent Inlet in the interior of the Canadian Arctic Archipelago, the Mackenzie River Delta/Eastern Beaufort Sea off Alaska, and the area between Franz Josef Archipelago and Novaya Zemlya Island in Russia.

The Bering-Chukchi-Beaufort and East Canada-West Greenland stocks had the greatest amount of historic refugia. They are also the two stocks that are recovering today.

It is likely that whale populations here were not depleted as severely due to being better shielded in refugia by the ice barriers. Hence, these stocks have been able to bounce back more strongly. Our hypothesis is additionally supported by inferences from modern and paleo-genomics of bowhead whales (details in the paper).
