This distinct form is flatter than other Echinocorys variants, making it a valuable addition to any echinoid or marine invertebrate fossil collection.

Fossil Type: Echinoid (Sea Urchin)

Species/Subspecies: Echinocorys scutata depressula

Geological Period: Late Cretaceous (~86.3 to 83.6 million years ago)

Geological Stage: Santonian

Formation: Upper Chalk (Chalk Group)

Location: Broadstairs, Kent, United Kingdom

Scale Rule: Squares/Cube = 1cm (Please refer to photo for exact sizing)

Specimen: The exact specimen shown in the listing photo is what you will receive

Authenticity: All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity

Geological and Paleontological Information

Echinocorys scutata depressula represents a distinct subspecies of the well-known chalk echinoid, notable for its depressed (flattened) profile and broad, slightly lower dome. These echinoids thrived in soft chalk marine seafloors, where they lived as infaunal deposit feeders.

Phylum: Echinodermata

Class: Echinoidea

Order: Holasteroida

Family: Holasteridae

Genus: Echinocorys

Subspecies: scutata depressula

Depositional Environment: Quiet, low-energy marine shelf; deposition of coccolith-rich chalk created ideal conditions for fossilisation of echinoids and other invertebrates

Morphological Features: Flattened, oval test (shell) with well-defined ambulacral petals; peristome and periproct typically located on flattened oral surface; delicate striae sometimes preserved

Biozone: Likely falls within mid to late Santonian ammonite or inoceramid biozones; important for stratigraphic correlation in UK chalk studies

Notable: This subspecies is less commonly encountered than scutata scutata and offers a refined morphotype for comparative echinoid studies

Why This Fossil is Special

A beautifully preserved flattened echinoid fossil from one of Britain’s most iconic Cretaceous formations, Echinocorys scutata depressula is an excellent study specimen and a visually striking display fossil. Its low profile and complete preservation make it a particularly collectible example.

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

Phymosoma texanum Fossil Regular Echinoid Lower Cretaceous Texas USA Genuine Specimen

Now available is a genuine Phymosoma texanum fossil, a classic regular echinoid (sea urchin) from the Lower Cretaceous Period (approximately 145 to 100 million years ago). This specimen was collected from the well-known fossil-bearing formations of Texas, USA, which have long yielded some of the finest Cretaceous echinoids in North America.

Geology & Origin:

During the Lower Cretaceous, the region now known as Texas was part of a shallow inland sea teeming with marine life. Organisms like Phymosoma texanum thrived on the sea floor, and when they died, their hard exoskeletons (tests) were buried by sediment. Over millions of years, mineralization preserved them in exquisite detail, creating this highly collectible fossil.

Fossil Type & Species:

Type: Fossil Echinoid (Regular Sea Urchin)

Species: Phymosoma texanum

Preservation: Very good, with well-defined test and tubercles

Features:

100% genuine, natural fossil specimen

Pygaster Fossil Regular Echinoid Jurassic Dorset UK Genuine Specimen

Featured here is a genuine Pygaster fossil, a well-preserved example of a regular echinoid (sea urchin) from the Jurassic Period (approximately 201 to 145 million years ago). This specimen was sourced from the famous fossil beds of Dorset, UK, part of England's renowned Jurassic Coast.

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.

Fossil Type & Species:

Type: Fossil Echinoid (Regular Sea Urchin)

Genus: Pygaster

Preservation: Very good, with detailed test and surface features
