Aquatic crustaceans of MANY types are fossilized in amber from 23 mya Mexico, but amber comes from tree sap - how did crustaceans get there??? We think the fossils may come from estuarine mangroves. Shown here are ostracods, copepods, isopods, and even CRAB. #Crustmas 🧪🦑 Paper list in next skeets

Ostracod: Thalassocypria cumangulus n. sp.: 4976/08, holotype, female. Scale bar 100 μm

Copepod: Ectinosomatidae (IHNFG–4899/Cop1); A1 = antennule, A2 enp = antennary exopod, A2 enp = antennary endopod, GDS = genital double-somite, AS = anal somite. Scale bar 200 μm. Photo from Francisco Vega

Isopod: Palaeospherarmadillo rotundus gen. nov. sp. nov., adult holotype (IHNFG-5302); General habitus, lateral view. Scale bar = 200 µm.

Crab: Sesarmidae. Dorsal view of cephalothorax, specimen IHNFG-4991. LCh = left cheliped, P2-P5 = pereiopods, RCh = right cheliped. Scale 3 mm

Ok so here comes a starter pack to find your favourite polychaete/annelid researchers. I have not yet found many of us, so let me know if you want to be included or know of others that should be included.

A gorgeous pic of a gorgeous worm, taken by my officemate who is out in the water way more than me. Oh how I wish there was a better english word for ”sprattel” than ”flail”. Hesionids (sprattelmaskar) definitely have one of the cutest Swedish common names🥹🪱

I recently described a new species of deep-sea polychaete found in high abundance on an abyssal wood-fall in the Clarion-Clipperton zone. Feel free to check it out to get your fill of wood, worms, and wonderful taxonomic mysteries! doi.org/10.1016/j.ds...
