Super cambrian (and pre-cambrian) aquarium world...

Featuring the new creatures Arandaspis and Hallucigenia, and the new blocks Wiwaxia and Charnia, as well as a fresh new look for Sacabambaspis 🙏 Also featuring Aquarium Glass from Fintastic (what used to be Yet Another Fish Mod because Curseforge doesn't like when you put the word "mod" in your title)

Tulaneia amabilia was an enigmatic Ediacaran animal that lived in what is now Nevada, USA just before the start of the Cambrian Period, about 540 million years ago.

Up to around 10cm across (~4"), its body was made up of a fan-shaped frill of airbed-like tubes, with tips that separated from each other and tapered to blunt points. Much like its close relative Ernietta it would have lived with its base buried in the seafloor sediment, and it was probably a suspension feeder catching organic particles in water currents.

One Tulaneia fossil specimen shows birfurcating tips, but it's unclear whether this was a common feature of this species or a developmental anomaly in this particular individual.

Day 6: Dickinsonia

Nobody:

Absolutely no one:

The Ediacaran: Flesh plants. Flesh plants! Great wobbling frisbee beasts! Flesh plants—

[img id] Digital cel-shaded art of a wibbly wobbly Dickinsonia, a weird wobbly lifeform from before the Cambrian era. It looks like a floppy frisbee with bilateral lines sectioning its body into many gelatinous ribs. It lives underwater surrounded by fleshy ‘plants’, including orange charnia with spots and neon green hylaecullulus. Since I’ve interpreted Dickinsonia as a transparent creature, the other life forms can be fuzzily seen through its body. This little scene is set on an isometric square chunk of sandy seafloor.

The Paleo Party Guest of the day is Tribrachidium!

Studies have shown that the 3 raised curved lobes would be functional at funneling water flow down into the feather like appendages on their body, possibly assisting in filter feeding.

Age: 558-555 MYA

Location: Australia, Ukraine, Russia, and India

My 25 years of palaeoart chronology...

Here's my 2024 Mistaken Point Ediacaran landscape reconstruction, created with Dr Duncan McIlroy and his team at Memorial University, Newfoundland. Featured are Beothukis, Fractofusus, Arborea, Charnia, Charniodiscus, Ivesheadiomorph, Primocandelabrum, Bradgatia, Thectardis, Lydonia, sea anemone , and microbial mats.

Drew some of the Ediacaran biota. Turned out really well, I don't really remèmber specifically *all* of them that I drew.
