Cringetober day 24 🐚Niche intrest!

I love and am really interested in the cambrium explosion! The critters and silly goobers are sooo cute and I'm always happy to learn more about them <<3

I sure hope Wels meets the icon, the legend, Opabinia Regalis

Today Welsknight is in a fossil meeting Opabinia Regalis!

Opabinia regalis

(temporal range: 508 mio. years ago)

[text from the Wikipedia article, see also link above]

Opabinia regalis is an extinct, stem group arthropod found in the Middle Cambrian Burgess Shale Lagerstätte (505 million years ago) of British Columbia.[1] Opabinia was a soft-bodied animal, measuring up to 7 cm in body length, and its segmented trunk had flaps along the sides and a fan-shaped tail. The head shows unusual features: five eyes, a mouth under the head and facing backwards, and a clawed proboscis that probably passed food to the mouth. Opabinia probably lived on the seafloor, using the proboscis to seek out small, soft food.[2] Fewer than twenty good specimens have been described; 3 specimens of Opabinia are known from the Greater Phyllopod bed, where they constitute less than 0.1% of the community.[3]

When the first thorough examination of Opabinia in 1975 revealed its unusual features, it was thought to be unrelated to any known phylum,[4] or perhaps a relative of arthropod and annelid ancestors.[2] However, later studies since late 1990s consistently support its affinity as a member of basal arthropods, alongside the closely-related radiodonts (Anomalocaris and relatives) and gilled lobopodians (Kerygmachela and Pambdelurion).[5][6][7][8][1][9][10]

In the 1970s, there was an ongoing debate about whether multi-celled animals appeared suddenly during the Early Cambrian, in an event called the Cambrian explosion, or had arisen earlier but without leaving fossils. At first Opabinia was regarded as strong evidence for the "explosive" hypothesis.[4] Later the discovery of a whole series of similar��lobopodian animals, some with closer resemblances to arthropods, and the development of the idea of stem groups suggested that the Early Cambrian was a time of relatively fast evolution but one that could be understood without assuming any unique evolutionary processes.

Protobulwark, the Shielded Seer Pokémon!

Type: Dark/Steel

Evolves from Photonia

Protobulwark spends its time hiding in reefs, waiting for a meal to pass in front of it just to nab with its extended claw. The armor on its back both provides defense and hides it from predators looking down from the water column.

My fave Cambrian animal and my fave deltarune character in one??? HELL YEAH

Everyone's favorite five eyed freak of the cambrian, Opabinia regalis. An animal that's weird even when compared to it's closer relatives.

Favorite now extinct animal?

omg that's such a hard question! i have so many! this is gonna be a long post...thank u for humoring me :)

but probably pretty obviously, my preference tends to be with invertebrates & aquatic creatures i feel like heteromorph ammonites are deeply underrated. like who doesn't enjoy a cephalopod with the most bizarre shell shape?

you could literally have the paperclip mollusk bro. there's also something about lobe-finned fishes and "fishapods" that i literally adore

tiktaalik and coelacanth being some of my all-time favorite creatures. you also really cannot go wrong with cambrian creatures! while anomalocaris gets a lot of well-deserved love, i propose appreciation for some of the other beautiful arthropods of radiodonta, like the humble opabinia regalis!

if you're looking for an actual dinosaur, i'm a big fan of theropods; my favorite being sinosauropteryx. i love their stripey tails! i've drawn these guys a handful of times, actually

i could keep going for like..probably a small novel's worth. i am by no means a professional, just a humble bio nerd <3

it’s Opabinia Regalis Wednesday

[lusynthiaa]

i hope i get an opabinia regalis and a surgery date for my orchi tomorrow 😊😊😊

[nekrops-shaped]

to Léan, do you go trick or treating? what do you want to dress up as?

"Not really trick or treating but this year school's throwing a Halloween party and dad's helping me build a costume!! i'm gonna be the coolest Opabinia regalis in the entire school!!!"

Spooky Askbox is open!
