My 25 years of palaeoart chronology…

The 2022 Korean translation of Locked in Time (by Dr Dean Lomax - Palaeontologist & published by Columbia University Press) commissioned me to colourise my 50 greyscale illustrations. Here's "The Transient Oasis," showing a colony of Seirocrinus crinoids drifting on deadwood.

Time for a new plate of creek treasures!

We've had a few little rains here recently, not enough to really make the creek flood much but still just enough to uncover a few new finds. Here we have a cow toe bone, a deer vertebrae, toy wheel, two-tone golf ball, a sweet little partial porcelain plate from an old doll's dish set (all that's left is the stem but it had a little flower painted in the middle—so cute!), hag stones, colorful bits of tumbled vintage glass, neck off an old soda bottle, some really nice chunky crinoids and other cool fossils, and...

...a couple pieces of uranium glass! Always love finding those! I think that is the first nugget of bonfire uranium glass I've found.

Did you know that Feather Starfish can regenerate their arms if they lose them? They can also detach their arms voluntarily to escape predators. Some feather starfish even host symbiotic animals like shrimps and crabs. They are amazing creatures that can swim, feed, and breathe with their arms.

Feather starfish are fascinating marine animals that belong to the class Crinoidea, which also includes sea lilies. They are not actually starfish, but they are related to them as they are both echinoderms. Feather starfish have a central body with many arms that are used for swimming, feeding, and respiration. They are usually found in tropical and subtropical waters, where they attach themselves to rocks, corals, or other surfaces. Feather starfish are also known as crinoids or comatulids.

Feather starfish are one of the oldest & most primitive species on earth. Their origins date back to the Ordovician Period, which began more than 488 million years ago. They can have as many as 200 arms, which branch numerous times and result in feathery pinnules. These arms can be of various colors, such as green, red or yellow. They can regenerate their arms if they lose them due to injury or predation. They can also detach their arms voluntarily to escape predators or to reproduce asexually.

Feather starfish host symbiotic animals like shrimps and crabs, which live among their arms and provide protection and cleaning services. Some feather starfish even have specialized structures called cirri that act as claws to hold their symbionts. They feed on planktonic particles that they capture with their tube feet and mucus on their arms. They then move the food along their arms to their mouth, which is located on the upper side of their body.

Feather starfish are amazing creatures that add beauty and diversity to the coral reefs. They are also important indicators of the health of the marine ecosystem, as they are sensitive to environmental changes. I hope you enjoyed reading about this wonderful & beautiful creature. 😊🙏

My 25 years of palaeoart chronology...

In 2020 I illustrated LOCKED IN TIME, written by Dr Dean R Lomax. Here's my "Transient Oasis" painting, depicting animals in and around a colony of crinoids growing on driftwood.

Yo I am about to have SO many lileep for my team

Joke aside, was just pretty darn excited about this find. I know they’re fairly common, but, someof the biggest crinoid stem fossils I’ve seen in person and this rock was chuck full of them. Think I’ll hold onto this.
