Small Echinoid Fossil - Salenia prestensis - Cretaceous, Aptian, Morella Spain - Genuine Specimen with Certificate

This listing features a beautifully preserved small echinoid fossil of the species Salenia prestensis, sourced from the Aptian stage of the Cretaceous period in the Morella region, Castellón province, Spain. This genuine fossil showcases the characteristic features of this extinct sea urchin, offering both scientific value and aesthetic charm.

Salenia prestensis belonged to a genus of regular echinoids that lived during the Lower Cretaceous. These marine echinoderms are recognized by their spherical to slightly flattened tests, covered with tiny tubercles and spines in life. Fossils of this genus are relatively rare and sought after, particularly from the rich sedimentary beds of the Iberian Peninsula.

After searching the echinodem fossils back from March to today, near end of April, now sorting out from the other fossils in my Collection, with adding the few flint urchins back from the last years to the others.

For showing them here with the newest finds.

Now there are two medium sized cups / bowls full with the garlic clove sized round echinoids.

It’s a lot now. If i had an aquarium tank or dry terrarium for reptiles, they were pretty decorations too.

For the photos or presentation use, i put the round or halfed ones in this shards of coloured flints with the fractured round mold, flat flint breaks a lot like this and are often to find.

They are nice podest or saucers for them & for round polished stones.

The cutted open side with blue, white and red ones are an great little contrast to the others.

So have the sadly destroyed urchin und some Parts an use and are to seen among with the other fossils in the Collection.

Fossil Type & Species:

Type: Invertebrate Fossil (Echinoid/Sea Urchin + Detached Spines)

Species: Acrosalenia hemicidaroides

Phylum: Echinodermata

Class: Echinoidea

Order: Cidaroida

Family: Hemicidaridae

Described by: d'Orbigny, 1850 (species known since the mid-19th century)

Geological & Stratigraphic Details:

Location: Neufchâteau, Vosges, France

Formation: Bajocian marine limestone/marl layers

Geological Stage: Bajocian, Middle Jurassic

Age: ~170–168 million years ago

Depositional Environment: Shallow marine carbonate platform, ideal for echinoderm preservation due to low-energy sedimentation and early calcite mineralisation

Biozone: Bajocian ammonite biozones (exact echinoid zonation not formally assigned)

Morphology & Features: This fossil displays key traits of Acrosalenia hemicidaroides:

Spherical to sub-hemispherical test (shell) with intricate tubercle patterns

Phymosoma Fossil Regular Echinoid Lower Cretaceous Spain Genuine Specimen

This listing features a genuine Phymosoma fossil, an excellent example of a regular echinoid (sea urchin) from the Lower Cretaceous Period (approximately 145 to 100 million years ago). This well-preserved specimen originates from the marine fossil deposits of Spain, known for their quality Cretaceous echinoderms.

Geology & Origin:

During the Lower Cretaceous, much of what is now Spain was covered by shallow seas teeming with marine life. Echinoids like Phymosoma lived on the seafloor and were occasionally buried quickly under fine sediment, leading to exceptional fossil preservation. Today, these fossil beds yield some of the finest echinoid specimens in Europe.

Fossil Type & Species:

Type: Fossil Echinoid (Regular Sea Urchin)

Genus: Phymosoma

Preservation: Very good, with detailed test and natural morphology

Features:

100% genuine, natural fossil specimen

Includes a Certificate of Authenticity

Hand-selected for its aesthetic and scientific value

The exact specimen pictured is the one you will receive

Scale cube = 1cm: See photo for accurate sizing

Why Buy From Us? We offer only authentic, professionally prepared fossils, carefully selected from trusted sources. Every specimen is accompanied by a Certificate of Authenticity, ensuring complete buyer confidence.

Geology & Origin:

The Jurassic Coast of Dorset is a UNESCO World Heritage Site, known globally for its rich fossil record and accessible sedimentary layers. During the Jurassic, this area was submerged under a warm shallow sea, ideal for marine organisms such as echinoids. As these creatures died, they were quickly buried under sediment and fossilized in exceptional detail. The result is a rare and scientifically valuable fossil like this specimen of Pygaster.
