Papiliomaris kluessendorfae, first reported in 1985 as the Waukesha "Butterfly Animal", was recently described as a strange bivalved arthropod with three pairs of large, feathery appendages. Some reports indicate it could reach up to 20cm wide.

Multiple lobopodian fossils from the Chengjiang Biota of Cambrian China, including a specimen of two Diania cactiformis, have been found stacked directly on top of each other.

Perhaps a snapshot into the courtship and reproduction of these ancient arthropod ancestors?

#Paleostream flocking! Nektognathus, Palaeocampa, Wudingloong(Sort by age). It is unclear if Wudingloong lived alongside quadrupedal sauropods

A really nice thread on a strange worm.

Meet Palaeocampa anthrax, a newly discovered Carboniferous lobopodian, and 150 year old mystery fossil!

Palaeocampa is an exceptional lobopodian - it lived in rivers and lakes, bristled with thousands of poisonous spines, and more. 🧵

Palaeocampa anthrax, a fossil worm first described from Carboniferous rocks in 1865 as a caterpillar, is redescribed as a freshwater aysheaiid lobopodian with unique sclerite armature and probable chemical defences.

Basically, they're this big mama here, but having lived directly in fresh water with spikes like spiky-boi caterpillars, a head shield, and presumably no ability to shoot glue.

They would definitely be fun to keep in an aquarium!

In Carboniferous lake of Montceau-les-Mines, Platysella descusi is trying to bother Palaeocampa anthrax. Palaeocampa curls up and bristles up in defense. Two Palaeocaris secretanae and single Nyranerpeton montceauense are swimming nearby.

🚨LOBOPODIAN ALERT!1!!!11!🚨 Palaeocampa – a fossil known since 1865 – redescribed & now interpreted as: geologically youngest of its kind (315-307 mya), lived in freshwater environments, & (most badass of all) had venomous spines. Great work by Richard Knect, @prehistorica.art, & colleagues. 🧪

Fossil once thought a caterpillar is now the oldest known nonmarine lobopodian
In a twist worthy of a detective novel, a long-misidentified fossil at Harvard's Museum of Comparative Zoology (MCZ) has emerged as a key discovery in early animal evolution.

Pulmonoscorpius, a 70cm long scorpion from Carboniferous Scotland.

A daytime predator, Pulmonoscorpius was equipped with large compound eyes on the sides of its head, and an enormous stinger. Here, it blends in with the forest, eating a lizard-like Westlothiana.

Comment on: Omnidens appendages and the origin of radiodont mouthparts

Are there really 2 species of Omnidens? I comment on the organization of the mouth of this Cambrian apex predator, and argue there is only one species, Omnidens amplus.
