My 25 years of palaeoart chronology...

Here's a study of Kingnites, commissioned in 2022 for a project I cannot talk about yet. Kingnites, is an exceptionally large (1m long) Silurian polychaete annelid.

Beautiful new study by Michael Bok, Macali & Garm on the high-resolution eyes of the enigmatic alciopid annelids, from Ponza island.
"Our results show that the eyes of alciopids possess the anatomical, morphological, and physiological properties requisite for high resolution tasks and object vision"

"Annelids represent one of the largest group of macroinvertebrates living within the mud covering the sea floor of #CCZ, both in terms of number of individuals and species."

Hydrostatic pressure is a dominant cue in the sea and many aquatic organisms are known to respond to changes in pressure, however the neuronal mechanisms have remained unclear.
We studied the larvae of the marine #annelid #Platynereis and found that they respond to increases in pressure by increased upward swimming.

"Researchers at Durham University, UK, and Northwest University, Xi'an, China, examined 15 exceptionally preserved fossils of the #annelid #worm #Iotuba #chengjiangensis dating from the early #Cambrian period 515 million years ago.

The fossilized remains included evidence of the worms' guts and kidneys and revealed they had an unexpectedly complex structure similar to that of other #annelid #worms."

#Annelids—or segmented #worms—diversified into different lineages some 200 million years earlier than previously thought and were part of the evolutionary leap known as the #CambrianExplosion.
