RARE: Turtle Exoskeleton Fossil – Barton Beds, Eocene, Whitecliff Bay, Isle of Wight UK

This listing features a rare fossilised turtle exoskeleton fragment, sourced from the Barton Beds at Whitecliff Bay, Isle of Wight, UK. This specimen dates to the Eocene Epoch, making it over 40 million years old and a significant piece of the UK’s palaeontological heritage.

Fossil Type:

Specimen: Turtle Exoskeleton (Shell fragment – likely carapace or plastron)

Represents a chelonian (turtle or tortoise) from the Eocene vertebrate assemblage of southern England

Geological Context:

Period: Paleogene

Epoch: Eocene

Stage: Bartonian (~41.3 to 38 million years ago)

Formation: Barton Group (formerly part of the “Barton Beds”)

Depositional Environment: Coastal lagoon and estuarine settings. The Barton Beds were laid down in a warm, subtropical marine and marginal marine environment rich in vertebrate and invertebrate fossils.

Morphological Features:

Curved or slightly flattened dermal bone typical of chelonian shell fragments

Surface may show granular texture or faint impressions of scute boundaries

Brown-grey fossilisation with natural wear and mineralisation from estuarine clays

Scientific Importance:

Fossil turtle material from the Barton Beds is rare and valuable for understanding Eocene coastal ecosystems in Britain

Specimens like this may be attributable to genera such as Trionyx or other soft-shelled or hard-shelled turtle lineages found in European Eocene sites

These fossils help reconstruct the palaeobiogeography of marine reptiles in the early Cenozoic

on fossil reconstruction.

omega, a prototype weapon against chaos, is dismantled due to its unstable nature and uncontrollable destructive capabilities. not many know the whole story of omega, but if you’re in wonderland you’ve likely encountered at least a fraction of it—or, if you’re unlucky, a fraction of omega itself.

the great beast is divided; it was torn asunder indiscriminately. unlike in destruction, the way omega would be reassembled matters.

horns, gills, tail fin, dorsal fins, claws, carapace… hundreds of fragments of the beast exist. in theory, one could attempt to start building off of any fragment, but it wouldn’t work out unless the reconstruction was begun on a core.

Heart, Mind, Eye: Emotion, Logic, Ethics. Core parts of omega that made it what it was.

these Cores are what construction could begin on. one cannot adhere two claws to eachother, but one could connect a claw to the Heart, a fin to the Mind, or a horn to the Eye. notably, it is best to connect pieces to the active Cores whilst the pieces are dormant and crystalline.

the more pieces that are tacked onto the Cores, the larger and stronger the new combined being—now called a Paleon—gets.

personality varies on which Core the Paleon is constructed off of. Cores will independently seek out pieces to combine with, but if attempting the reconstruction, be careful which Core you help. Heart is overly emotional, Mind uses apathetic logic, and Eye’s sense of justice and ethics are firm.

it would be better if the Cores combined first before re-adorning their body, so omega’s self is whole… but considering how widespread omega’s fragments are, each Core will take what they can get. fundamentally, the Cores desire to be whole and will not turn down any opportunities to accomplish the feat.

The tuzoiids were an enigmatic group of Cambrian invertebrates known mostly just from their spiny bivalved carapaces. Although hundreds of fossils of these arthropods were discovered over the last century or so, only vague fragments of the rest of their bodies have been found even in sites usually known for preserving soft tissue impressions.

…Until late 2022, when several new specimens from the Canadian Burgess Shale deposits (~508 million years ago) were described showing tuzoiid anatomy in exceptional detail, finally giving us an idea of what they looked like and where they fit into the early arthropod evolutionary tree.

Tuzoiids like Tuzoia burgessensis here would have grown up to about 23cm long (~9"). They had large eyes on short stalks, a pair of simple antennae, a horizontal fluke-like tail fan, and twelve pairs of appendages along their body – with the front two pairs at the head end being significantly spinier, and most (or all) of these limbs also bearing paddle-like exopods.

The large carapace enclosed most of the body, and was ornamented with protective spines and a net-like surface pattern that probably increased the strength of the relatively thin chitinous structure.

Together all these anatomical features now indicate that tuzoiids were early mandibulates (part of the lineage including modern myriapods, crustaceans, and insects), and were probably very closely related to the hymenocarines.

Tuzoiids seem to have been active swimmers that probably cruised around just above the seafloor, with their stout legs suggesting they could also walk around if they flexed their valves open. The arrangement of their spiny front limbs wasn't suited to grabbing at fast-swimming prey, but instead may have been used to capture slower seafloor animals or to scavenge from carcasses.

I was trying to vaguely imagine what a Hisuian regional form time capsule made by Akari/Rei (and maybe Ingo too if he learns about the extinctions) might look like. My brain decided “actually no, don’t make it vague, draw the time capsule exactly” and then held me hostage and wouldn’t let me focus on anything else until I did so.

Notes under the cut:

A time capsule put together by the future folk who got stuck in Hisui, hoping that the DNA samples inside will survive a couple hundred years and make it to the future to be resurrected like the fossil pokémon are. Also included are traditionally made pokéballs, due to the assumption that there’s probably very few surviving ones and that archaeologists would love them, along with 2 books left with the intent of preserving knowledge that’d likely been forgotten. The items are all in individually padded compartments.

Based on the tech in Galaxy Hall, I’m assuming the Galaxy Team has the means to forge (or order from overseas?) a metal container that is watertight (and hopefully airtight as well). Idk a lot about time capsule construction, but their hope is that they create a container that’ll prevent the decay of the more fragile items in the box. Or at least hold the decay off long enough for the capsule to be opened.

List of Items:

Decidueye feather, fur from Typhlosian’s tail, fur from Samurott’s ‘whiskers’

Black Augurite, carapace sheds from Kleavor and Scyther

Peat Block, fur from Ursaluna, Ursaring, and Teddiursa

Quills from Qwilfish and Overqwill

Dried petals from Lilligant and a dried leaf from Petilil

Feathers from Rufflet and Braviary

Rock fragment from Avalugg

Bottles of slime from Goomy, Sliggoo, and Goodra

Fur from Zorua and Zoruark

Scales from male and female Basculin, as well as male and female Basculegion

Fragments from Voltorb and Electrode (naturally lost during self-destructs?)

Sneasel and Sneasler fur

Wyrdeer fur and a fragment of a shed antler, Stantler fur

Growlithe and Arcanine fur

Full set of pokéballs and the tumblestones they’re made from

A first edition Hisuian Pokédex

A book of notes on all the items in the box; it lists the items and their usage, as well as notes on the care and evolution requirements of the pokémon represented.

*Samples from native non-regional forms are included, just in case the pokémon are genetically different enough in the future that they truly cannot evolve into these Hisuian forms even with the items and knowledge to do so. (Does not include Bergmite. Most of Bergmite is just normal ice. Idk where it keeps its DNA)

Fossil site reveals giant arthropods dominated the seas 470 million years ago

Fossil site reveals giant arthropods dominated the seas 470 million years ago

Discoveries at a major new fossil site in Morocco suggest giant arthropods — relatives of modern creatures including shrimps, insects and spiders — dominated the seas 470 million years ago.

Early evidence from the site at Taichoute, once undersea but now a desert, records numerous large “free-swimming” arthropods.

More research is needed to analyse these fragments, but based on previously described specimens, the giant arthropods could be up to 2m long.

An international research team say the site and its fossil record are very different from other previously described and studied Fezouata Shale sites from 80km away.

They say Taichoute (considered part of the wider “Fezouata Biota”) opens new avenues for paleontological and ecological research.

“Everything is new about this locality — its sedimentology, paleontology, and even the preservation of fossils — further highlighting the importance of the Fezouata Biota in completing our understanding of past life on Earth,” said lead author Dr Farid Saleh, from the University of Lausanne and and Yunnan University.

Dr Xiaoya Ma, from the University of Exeter and Yunnan University, added: “While the giant arthropods we discovered have not yet been fully identified, some may belong to previously described species of the Fezouata Biota, and some will certainly be new species.

“Nevertheless, their large size and free-swimming lifestyle suggest they played a unique role in these ecosystems.”

The Fezouata Shale was recently selected as one of the 100 most important geological sites worldwide because of its importance for understanding the evolution during the Early Ordovician period, about 470 million years ago.

Fossils discovered in these rocks include mineralised elements (eg shells), but some also show exceptional preservation of soft parts such as internal organs, allowing scientists to investigate the anatomy of early animal life on Earth.

Animals of the Fezouata Shale, in Morocco’s Zagora region, lived in a shallow sea that experienced repeated storm and wave activities, which buried the animal communities and preserved them in place as exceptional fossils.

However, nektonic (or free-swimming) animals remain a relatively minor component overall in the Fezouata Biota.

The new study reports the discovery of the Taichoute fossils, preserved in sediments that are a few million years younger than those from the Zagora area and are dominated by fragments of giant arthropods.

“Carcasses were transported to a relatively deep marine environment by underwater landslides, which contrasts with previous discoveries of carcass preservation in shallower settings, which were buried in place by storm deposits,” said Dr Romain Vaucher, from the University of Lausanne.

Professor Allison Daley, also from the University of Lausanne, added: “Animals such as brachiopods are found attached to some arthropod fragments, indicating that these large carapaces acted as nutrient stores for the seafloor dwelling community once they were dead and lying on the seafloor.”

Dr Lukáš Laibl, from the Czech Academy of Sciences, who had the opportunity to participate in the initial fieldwork, said: “Taichoute is not only important due to the dominance of large nektonic arthropods.

“Even when it comes to trilobites, new species so far unknown from the Fezouata Biota are found in Taichoute.”

Dr Bertrand Lefebvre, from the University of Lyon, who is the senior author on the paper, and who has been working on the Fezouata Biota for the past two decades, concluded: “The Fezouata Biota keeps surprising us with new unexpected discoveries.”

The paper, published in the journal Scientific Reports, is entitled: “New fossil assemblages from the Early Ordovician Fezouata Biota.”

It's time for Trilobite Tuesday! Despite being covered in thick calcite carapaces, which often gave them the appearance of undersea battle tanks, trilobites were, in fact, rather delicately constructed creatures. Evidence of this apparent design “flaw” is pervasive throughout the fossil record, where disarticulated trilobite fragments, as seen in this Dalmaniites slab from Sweden, far outnumber the remains of complete specimens. In a number of fossiliferous biozones around the globe, including those in British Columbia, Morocco, and the Czech Republic, independent pygidia, cephala, and thoracic segments virtually litter the sedimentary strata…with often nary an articulated trilobite to be found.
