A colored-pencil sketch of an early-Pleistocene red-backed vole (Clethrionomys sibiricola) on a blank white background. The vole is standing with one forelimb raised up in a relatively neutral pose, with its tail curling around. Its fur is generally rusty brown with a more reddish back.
Quick sketch of the newly described Clethrionomys sibiricola, the early-Pleistocene ancestor of the Northern Red-backed Vole (Clethrionomys rutilus). Its fossils (several teeth and a partial mandible) are known from Western Siberia. #sciart #paleoart #pleistocene #vole

06.01.2026 16:24 โ ๐ 5 ๐ 0 ๐ฌ 0 ๐ 0A diagrammatic reconstruction of Colymosathon ecplecticos in lateral view. A scale bar indicates that the length of the carapace is 5.2 mm. It shows appendages 1-6 in both lateral and dorsal view. It shows appendage 7, the penis, anus, furca, and gills in lateral view. Appendage 2: 6-7 setae correlating to podomeres on distal half of exopod. Appendage 3: 8-10 endites on total limb stem (doesn't specify how many on basis and coxa respectively). Appendage 4: Unknown amount of endites after the larger 2. Appendage 5 endopod: "-has several setiferous medial endites and terminates distally in a cluster of about 5 tiny processes." Appendage 5 expod: >16 processes on the exopod. Other notes: Many of the appendages have an unknown amount of podomeres. No description of the distal end of appendage 7. "A sinuous finger like process of unknown homology projects from the posterior part of the furca."

A diagrammatic and a life reconstruction of Colymbosathon ecplecticos, an Ostracod of the Silurian Herefordshire Biota.
Take the reconstruction with a grain of salt though; the paper was unable to discern the segmentation for many of the limbs, so that is somewhat guesswork.

There is also a nonspecific Crinoid on the left and a nonspecific, hard to see Graptoloid in the top right. Crinoids and Graptoloids are known from the Coalbrookdale Formation, but none of them have been described.
