Geological and Paleontological Information

Tentaculites ornatus is a small, cone-shaped fossil characterized by its fine transverse ornamentation and radial symmetry. It lived on the seafloor or floated in the water column during the Silurian period. The exact classification of Tentaculitids remains debated, but they are a common component of Silurian marine assemblages, especially in the Wenlock Limestone.

Kingdom: Animalia (uncertain phylum, traditionally placed within Mollusca or Lophophorata)

Class: Tentaculita (extinct)

Order: Tentaculitida

Family: Tentaculitidae

Geological Stage: Wenlockian (mid-Silurian)

Depositional Environment: Shallow, warm marine shelf; low-energy carbonate platform with rich biodiversity, including trilobites, brachiopods, corals, and cephalopods

Morphological Features: Small, conical shell with fine growth lines and ornamented with distinct annulations; typically tapers to a pointed apex with broader apertural end

Notable: Wrens Nest is a globally recognized site of Silurian marine paleontology and was instrumental in the historical development of stratigraphy and paleobiology in the 19th century

Biozone: Likely associated with Wenlockian graptolite and brachiopod biozones (e.g., Cyrtograptus biozones), though precise zonation is layer-dependent

Identifier: Originally described in 19th-century literature; specimens from Dudley are among the best documented in Britain

Why This Fossil is Noteworthy

Although often confused with juvenile orthocones, Tentaculites ornatus represents a distinct and fascinating fossil group. Its presence in the Wenlock Limestone Formation connects it to one of the most fossiliferous and historically significant Silurian deposits in the world.

Take home a real piece of the Silurian seas of ancient Britain with this beautifully preserved Tentaculites ornatus fossil from Wrens Nest, Dudley—a unique glimpse into life over 425 million years ago.

[alphynix]

Ophiocistioids were a group of weird and poorly-understood echinoderms which lived between the early Ordovician and the late Triassic, about 475 to 233 million years ago. Related to modern sea cucumbers, they were squat dome-shaped creatures with clusters of tentacle-like scaly tube feet, and have been compared to the bizarre fictional monsters of H. P. Lovecraft's Cthulhu Mythos.

So it's not really surprising that one of them has been named Sollasina cthulhu.

But unlike its namesake this "monster" was actually tiny, only 3cm across (1.2"). It was discovered in the fine-grained Wenlock limestones of the UK, and dates to the late Silurian, about 430 million years ago. Its exceptionally well-preserved state makes it the first ophiocistioid with known fossilized internal structures, including evidence of its water vascular system.

Unfortunately this high level of detail comes at a cost — the tiny Wenlock fossils are preserved in three dimensions inside hard concretions and are almost impossible to extract or interpret from split-open cross-sections, and highly expensive CT scans don't give a good enough resolution. So the only way to actually "see" them is to destroy them, grinding away a tiny layer at a time and taking a photograph at each step, then assembling a digital reconstruction from the hundreds of slices.

A lovely #calymene blumenbachi from the #Wenlock limestone for #trilobite Tuesday, this one is from our #teaching collection @oxuniearthsci #fossil #fossils #GeologyJohnson #geology #palaeontology #paleontology #paleozoic #invertebrates (at Oxford University Earth Sciences) https://www.instagram.com/p/B3WVPwvJgJ6/?igshid=17y8helvk3bf6

It’s time for Trilobite Tuesday! The Silurian exposures of the English Midlands have been yielding amazing trilobite specimens for centuries. Those from the Wenlock limestone formations near the town of Dudley are among the most beautiful in the world. One particular species, Calymene blumenbachii (pictured), has become synonymous with the area, and the coat of arms for the Dudley County Borough Council proudly includes an illustration of the fossilized local “locust.” More than 80 trilobite species have been discovered and described from the area’s most famous collecting locale, Wren’s Nest, where the 420-million-year-old strata has produced hundreds of magnificently preserved complete specimens. Now designated as a Site of Special Scientific Interest (where digging for fossils is prohibited), Wren’s Nest remains one of the most studied and storied of European fossil locales.

[maidstonemuseum]

The fossil trilobite, Calymene blumenbachii is also know as a Dudley Locust, though the quarry workmen had probably never seen a real locust. The best specimens, like this one, are almost exclusive to the Wrens Nest Quarry in Dudley. It is part of the Wenlock Edge limestone but the rest of it was formed under slightly different conditions, probably close to land. Although trilobites are found elsewhere they are not so well preserved. This species is Sillurian in age, formed around 450 million years ago. Trilobites are now extinct, but their relatives, insects, crabs and spiders still exist. Many more fossils can be seen on 30 September 2017 at the Fossil Roadshow in Maidstone Museum.
