#TrilobiteTuesday. Few things I miss about the Midwest- going to the local Ordovician limestones & collecting trilobites whenever I wanted to is one of them.... #paleontology

#TrilobiteTuesday

Here is part of the body of quite a large trilobite known as Paradoxides spinosus. This specimen comes from the Middle Cambrian (Drumian) Jince Formation from the Czech Republic. Paradoxides is one of the largest trilobites known from the Cambrian period.

#TrilobiteTuesday is a brief respite from Trump's bloodlust. But we still need to keep our eyes on the ball.

Welcome back to #TrilobiteTuesday

Here is the positive and negative impressions of Bathyuriscus fimbriatus. This specimen comes from the Middle Cambrian (Drumian) Marjum Formation in House Range, Utah. The Marjum is age equivalent to the Wheeler Shale but with slightly better preservation.

Welcome back to another #TrilobiteTuesday

Here is the positive and negative impression of Amecephalus idahoense. This specimen comes from the Middle Cambrian Spence Shale Member of the Langston Formation in Idaho. The spence shale is a unique group of rocks that preserves soft bodied organisms.

#TrilobiteTuesday From the public galleries of the South Australia Museum in Adelaide, a very fine fossil of the Cambrian trilobite Redlichia rex.

Apparently there is such a thing as #trilobitetuesday (I approve), so for the 9th day of #Crustmas not one, but two Ceratoserolis trilobitoides (plus I miss days, so...)

a light pink hermit crab stands in like. idk, imagine they're about to start dancing in the musical chicago, with legs all spread out? That's how they're standing. On a leaf.

It's day 9 of the invertebrate macro photo #ArtAdventCalendar.

Here, have a hermit crab 😘

Meet Amathillopsis spinigera! 🦐 Samples from the Ocean Census #ArcticDeep workshop and a 2024 Polarstern expedition revealed this species turning up far beyond its known depths. It’s now recorded from 11–3182 m thanks to 46 new findings.

Salps are gelatinous animals that live in the open ocean and often form long chains, with new animals budding off from others in the chain. This rarely observed Helicosalpa virgula was captured on camera at a depth of 282 meters (925 feet).
