Parascutella neuvillei Fossil Echinoid (Sea Urchin) – Miocene – Aquitaine, France

Parascutella neuvillei Fossil Echinoid (Sea Urchin) – Miocene – Aquitaine, France

About the Fossil:

This well-preserved Parascutella neuvillei fossil echinoid originates from the Miocene epoch (~23-5.3 million years ago) and was discovered in Aquitaine, France. Parascutella is an extinct genus of sand dollars (a type of echinoid), distinguished by its flattened, disc-like shape and petal-like patterns formed by ambulacral grooves.

During the Miocene, these echinoids thrived in shallow marine environments, where they lived partially buried in sandy seabeds, using their specialized spines to move and filter-feed on organic material. Their unique structure and evolutionary adaptations make them important indicators of paleo-marine environments.

Geology & Formation:

Geological Age: Miocene (~23-5.3 million years ago)

Formation: Marine sedimentary deposits

Location: Aquitaine, France

Preservation: Exceptional fossilization with clearly defined petal-like symmetry and fine surface details

Sea Urchin Fossil

Curio collection earrings! Just listed a backlog of earrings (link in bio if you want one!) Featuring doll eyes, snake bones, beetle shells, sea urchin spines, and more!

Found this very nice, medium size echinoid on the sand road tracks directly near the field.

Saw it and in that moment I thought only wtf, here so near of those tracks? In front of me now ???? Colored brown like it’s sandy terrain.

Intact, full condition without cracks no fissures no damaged open parts with unknown flint core color. Has the size of an tangerine. 🍊

All of the outer shell pattern is intact, you can seen all sides, the dots, armored parts and star shape, near round like an tangerine but one side is crushed from long time ago, since the fossil formed from the minerals in the once not filled exoskeleton. Brown colored fint like the sand.

I‘am very very glad and happy about this stunning nice find. An Incredible Echinoid.

Guess who is a great big nerd and bought a great big fossil today

#2496 - Fellaster zelandiae - Snapper Biscuit

AKA Cake Urchin.

Fellaster zelandiae is and was endemic to Aotearoa - the other species, incisa, was found in Australian waters.

Sand dollars (also known as sea cookies, sea biscuits, or pansy shells) are flat, burrowing sea urchins in the order Clypeasteroida. They first evolved from other irregular echinoids in the Jurassic, and live in temperate and tropical oceans worldwide, using their velvety spines to burrow through soft sediments, feeding on algae and organic matter. Some species prop themselves up sideways to feed on passing plankton.

Unlike most echinoids, sand dollars have developed a secondarily bilateral symmetry, including an anus towards the rear of the animal instead of centrally on top, as part of their evolution into burrowing animals.

Some sand dollar larvae have been shown to clone themselves if they detect the mucus of predatory fish in the water.

More photos are coming.

Have an free Sunday with Fossils & Coffee after.

Found probably three flints with mussels, two shards from urchin molds.

And then the fragmented & intact urchins. Three have bad effect from the naturell erosion progress, but it‘s the work of time, so it‘s fine.

The one little in gray urchin fossil is intact.

Also found the matching pieces of an brocken intact echinodea family speciemen.

I was thinking about clothes today and two movies popped into my head. "The Banshees of Inisherin" and "Ammonite" with Kate Winslet. Her clothes are fantastic in this movie. The knitted sweaters in "The Banshees of Inisherin" are also fantastic. But "Ammonite" reminded me of something last summer. I found 12 Hühnergötter at once on the beach and picked up all the stones I found beautiful. I put them in a pile in front of my tent to see which ones I would keep later. At some point, the guy camping next to me approached me and asked about the stones I had collected. And I said. Oh that's nothing, I have no idea and just put in what I like. But he sounded like he had a clue and was genuinely interested. So we looked through the stones together and found a piece of a fossilized sea urchin and a piece of an octopus. It turned out he was from the town I moved away from 9 years ago and is a biologist. He was there to watch birds. He had an incredibly large pair of binoculars with him, with which I could see the craters on the moon. It was a wonderful encounter. Later, a storm came up and I woke up in the morning in a 10 cm deep puddle. But my tent held tight :)

Makes me miss Ireland even more than I already do.

Found a fossilised sea urchin on a sidewalk 💙🪨 They can be found almost everywhere where there's stones and rocks, not just at beaches. It’s added to my collection of them now 🥰

She told me it was a stone carved with magic symbols by an ancestor long ago.

HOLECTYPUS DEPRESSUS Fossil Echinoid Sea Urchin Jurassic Cornbrash Somerset UK Authentic Specimen

This listing features a well-preserved fossil echinoid (sea urchin) of the species Holectypus depressus, collected from the Cornbrash Formation in Somerset, United Kingdom. This authentic Jurassic marine invertebrate fossil is provided with a Certificate of Authenticity, and the photo shows the exact specimen you will receive.

Holectypus depressus belongs to:

Order: Holectypoida

Family: Holectypidae

This echinoid lived during the Bathonian Stage of the Middle Jurassic Period, approximately 168–166 million years ago. The Cornbrash Formation consists of marine shelly limestones and mudstones deposited in a shallow marine, inner shelf environment that supported a diverse array of invertebrate life.

Morphological Features:

Flattened, oval test (shell) with a low dome profile

Petaloid ambulacra with finely impressed pore pairs

Oral surface flattened with distinct peristome

Smooth to lightly granulated surface, often symmetrical

These features suggest an infaunal or semi-infaunal lifestyle, with the organism likely burrowing or living on soft marine sediments.

Specimen Details:

Species: Holectypus depressus

Fossil Type: Echinoid (Sea Urchin) Test

Geological Unit: Cornbrash Formation

Geological Age: Middle Jurassic (Bathonian Stage)

Location: Somerset, United Kingdom

Depositional Environment: Shallow marine shelf, calcareous muds and shelly limestones

Family: Holectypidae

This is a fine example of a Jurassic echinoid fossil from a historically significant geological unit in the UK, ideal for fossil collectors, educators, or anyone with a passion for ancient marine life.

on my way home! cant wait to see momo again. i ended up drawing more than probably all the previous months together, and even felt inspired to break out the watercolors again.

I'm so jaleous of all of you, so much those who live close to the coasts and beaches, in these windy stormy days in November and December. You all amber sea glass and sea urchin - coral fossils seeking rock hounding and beach visitors. 🌊 🥺😭

Unfortunately, i have no opportunity or time to travel neither the coast currently or soon, such as the Baltic Sea.

Ich beneide euch alle, jede und jeder so sehr diejenigen die nah an den Küsten und Stränden leben, in diesen windigen Sturmtief Tagen im November und Dezember. Ihr Bernstein, Seeglas Korallen und Seeigel suchende Sammler. 🫠😭

Habe zeitlich leider keine Gelegenheit aktuell oder demnächst an die Küste zu reisen wie Ost oder Nordsee.

I recently was given Rocks! Fossil Rocks of long Dead Sea urchins!

They are very cool!
