Day74 of photoshopping @lastweektonight.com 's John Oliver with fossils in the hopes that he saves the Paleontological Research Institution
It could be a beautiful partnership! Fossil is the blastoid Pentremites robustus(PRI44909), others are H. sapiens.

On the 8th day of fossils, my true love gave to me...
8 Hyperoblastus blastoids from Milan, Michigan.
Blastoids are echinoderms related to starfish, sea urchins and crinoids. At some localities they are common. They are very rare at the Devonian Silica Shale Milan location.

I also found my best Hyperoblastus from the Devonian Thunder Bay limestone. This is a blastoid related to starfish and sand dollars with 5 point symmetry.
The other specimens in my collection are a bit weathered from rolling on the beach. This one must have been exposed over the winter freeze/thaw

This was my favorite find at MAPS. Eleutherocrinus cassedayi is a stemless blastoid from the Devonian Hungry Hollow Mb. of Arkona, Ontario. It laid on the ground, so one side is flat. There is only one species of Eleutherocrinus in the entire world.
I found 2 of them at MAPS.

Spent some time in my prep room tonight and cleaned up some echinoderms from the Mississippian Burlington Limestone.
This one isn't quite done, but there was a hidden second blastoid. It was a nice surprise.

Photoshopping @lastweektonight.com John Oliver onto fossils until the Paleontological Research Institution secures their funding!
Fossil specimen of the blastoid Pentremites godani from the Mississippian Paint Creek Fmt of St. Clair County, IL (PRI 70771). Comedian is H. sapiens. Not to scale.

I got some museum putty so I’m making more permanent homes for my lettercase tchotchkes. We have a miniature kid’s book fro my grandma’s dollhouse, born coral fossil, blastoid fossil, mystery tooth, mammoth ivory D6, Eocene mammal jaw, dino fossil D20, and Lego Sebulba.

I bought a light box to take better pictures of fossils. Still working on the lighting, but it's pretty nice.

So far, the theme of my 2026 publications seems to be "fish making poor life choices." 🧪
In this example, we have multiple blastoid specimens that seem to preserve partially healed fish bite marks: www.scup.com/eprint/AQIF3...

Crunchy on the outside, chewy on the inside: evidence for vertebrate predation and recovery in the Mississippian blastoid Pentremites spicatus
Predation acts as a major evolutionary selective pressure, but this process must often
be approached indirectly in the fossil record. Predation and consumption are often
destructive processes for the ...

One of the smallest Foundryon Relics is this small Blastoid inspired fidget. It is pure steel and it is resting with its Relic Custodian in Los Angeles.

Had the chance to draw Blastoid, Blitz, and Bubbles for the collaboration.
Glad to be part of this project with other talented artists!

Here is the Blastoid Penteremites godi. This comes from the Upper Mississippian (Lower Carboniferous) Ridenhower Formation from Floraville, Illinois. Blastoids are an extinct group of Echinoderms that were sessile filter feeders.

Blastoids have a long stem like crinoids, but instead of arms to filter food, they have delicate hair-like brachioles - both are rarely preserved.
The first pic is from Arkona, Ont. with stem. The last pic is from Kentucky with brachioles and also has preserved color patterns.

Of the 8 blastoids I've found at Milan, this is the only one attached to matrix. Would you have seen it?
If I find just one blastoid on a trip here, it's been a great day.
