Building a Brachiopod

Timelapse video showing the 3D modelling and texturing process of a Brachiopod (Deloprosopus, the top shell looks kinda like a cashew nut, the bottom one is more regular shell-shaped. inside are cone Spiral shaped filtering organs called lophophores,)

various vetulicolians are up on my Youtube channel

alt: video shows vetulicolians in an aquarium setting with the glass aquarium Background and sometimes the water surface.

The first three vetulicolians have a rectangular fish like 'head' shape with no eyes, a small hole for a mouth, and a grooved line running through separating the top and bottom half of the body. Along the grooved lines there are five holes identified as gill slits, on top of the body is a small dorsal fin similar to a shark's in shape. Protruding out after the dorsal fin is a paddle like segmented tail that propels the body forward. The second one is more rectangular in shape hence the name rectangulata, while the third one, V.cuneata has a beak like protrusion instead of a rectangle shaped head. Fourth one shows shenzianyuloma, it has a more pomfret-like silhouette. Fifth is Nesonektris, it has no dorsal fin and the tail doesn't protrude out of the top half of the body, it looks more continuous with the body. Sixth shows pomatrum, its body is tube like with a tadpole shaped tail. Seventh briefly shows skeemella, still Unclear if it's really a vetulicolian. It has a smaller head followed by a long many segmented tail. The YouTube commenters have pointed out it looks somewhat like a sperm...

Tardisia broedeae was a small arthropod recently discovered in the 308-million-year-old Late Carboniferous Mazon Creek fossil beds in Illinois, USA.

Its anatomy has distinctive features of vicissicaudatans (close relatives of the trilobites), but its presence in Mazon Creek makes it by far the youngest known member of this group – indicating a previously-unknown ghost lineage of around 100 million years, and inspiring its name based on the time-travelling TARDIS in Doctor Who.

About 1.5cm long (~0.6"), Tardisia had an oval segmented body ending in a pair of pointed "tail" appendages. It also appears to have been eyeless, although some vicissicaudatans had eyes on their undersides so this might just be an artifact of preservation.

Rectangl

(alt:)

vetulicola rectangulata swimming, it's an early stem chordate, somewhat tadpole-like motion, the 'head' in rectangulata has a rectangle shape in the front and more oval at the back, there's a line dividing the top and bottom half of the 'head' which contains five round openings identified as gill slits. It has a pointy Shark like dorsal fin at the top followed by a flat segmented tadpole like tail sticking out after the top dorsal fin)

Gross ass behavior from the Devonian community, smh

Grossaspis would like you to know that you hurt its feelings.

Some pics I snapped while I was at a cafe in the mountains and it started pouring, so all the bugs started swarming the windows to seek shelter

Motherships

Alt: in reality these vetulicolians are about 5cm long, they look like tadpoles that's been flattened on the sides, oval fish like 'head' silhouette with 5 round holes identified as gills on the side and segmented tail in the back that flattens out like a paddle. The oval head portion also tapers very thinly at the rim that they look like fins, the top part has a triangular pointy bit that looks like a shark's dorsal fin

These Cambrian oddities aren't vertebrates and the consensus seems to place them as stem chordates.

The video depicts them as large looming figures in murky water, with little brachiopods (bivalved shelles animals that's not a mollusk) in the foreground

a lil sneak peak on what i'm working on now 👀

alt: Camera (shallow focus distance) pans from right to left, close up to an approximately 2cm long trilobite slightly moving forward while its antenna and butt jiggles (palaeolenus) among a tight cluster of Neobolus brachiopods (not mollusks but they have a similar bivalved shell that resembles clams except the top and bottom shells are not exactly the same, but the left and right is symmetrical unlike in clams). on some of the brachiopod shells are even smaller parasitic organisms of unclear affinity, only recognizable from their conical pointy tubes

Taco night

(alt: Video render of Isoxys minor, Middle cambrian bivalved arthropods shown here in orange with a dark aquarium background

Isoxys has a taco shaped carapace enveloping it's entire body like a copepod, the open part of the 'taco' pointing down, its segmented body is completely hidden inside the 'taco' with tiny swimming legs reminiscent of those found in Triops, barely visible poking out of it. and two front appendages that look somewhat like an anomalocaris' claws but pointing up although they are not closely related to anomalocaris. It also has two eyes visible on the front, poking out of the carapace

Tl;Dr a swimming taco with segmented 'tusks' on the front and shrimp like legs poking out the bottom.

The video depicts them flitting around the aquarium from a close-up view with a short focus distance since they are typically only 1 cm long)

Anyone here who's into Trilobites, i got a video for you

Based on the new trilobite soft tissues discovered in a Middle cambrian Morrocan specimen that's been buried in a volcano.
