Any paleontologists out there that has advice on how one identifies the species of a fossil? I am looking at everything from microfossils (foraminifera), molluscs and corals. Is there a manual that teaches how to do this effectively? I am but a mere modeller!

This is perhaps my last posts regarding the size estimations of Nanaimoteuthis haggarti, pretty much because there is nothing more to attempt to change their results until somebody come to make a more concrete argument of the results, for now I stick with a conservative size

A new #Triassic austrolimulid from #Poland presents insight into xiphosurid evolution and palaeobiogeography at the dawn of the Mesozoic led by @jaudycki.bsky.social and with @grzegorzniedz.bsky.social: peerj.com/articles/209... @peerj.bsky.social #paleobiology #evolution

Palaeobiogeography of Triassic horseshoe crabs.
Palaeogeography of the world is reconstructed at 245 Ma (Anisian, Middle Triassic) and displayed using Mollweide projection, with a close-up of the Central European Basin System. The extents of shallow seas (light blue), landmasses (pale yellow) and mountain ranges (orange) are reconstructed based on Cao et al. (2017). Symbols represent Triassic localities that have yielded horseshoe crab fossils, their ages, and taxonomic assignment. The palaecoordinates of the xiphosurid localities are also reconstructed at 245 Ma for consistency. Simplified reconstructions of austrolimulids are displayed for context and comparison: 1–Polonolimulus zaleziankensis from the Lower Triassic (uppermost Induan/lowermost Olenekian) Zalezianka-Gózd locality, Poland; 2–Psammolimulus gottingensis from the Lower Triassic (Olenekian) Solling Formation, Germany; 3–Batracholimulus fuchsbergensis from the Upper Triassic (Norian/Rhaetian boundary) Exter Formation, Germany; 4–Attenborolimulus superspinosus from the Lower Triassic (upper Olenekian) Petropavlovka Formation, Russia; 5–Vaderlimulus tricki from the Lower Triassic (lower Spathian, Olenekian) Thaynes Group, USA; 6–Austrolimulus fletcheri from the Middle Triassic (lower Anisian) Beacon Hill Quarry, Hawkesbury Sandstone, Australia; 7–Dubbolimulus peetae from the Middle Triassic (lower Anisian) Ballimore Formation, Australia; 8–Tasmaniolimulus patersoni from the Lower Triassic (lower Induan) Jackey Shale, Tasmania (Australia). Since the investigated xiphosurid localities differ stratigraphically, their geographical position relative to continental boundaries and shallow seashores are approximated. The display window on the map showing close-up boundaries is not square due to employed map projection.

Rejecting the radiating neuromeric organization of Mollisonia, Bolton et al. do not recognize that Gaussian blurring can reveal cryptic arrangements: digital defocusing of neural traces in the fossil’s tilted part reveals seriate tiling.

'Satan's Lyre' #graptolite #paleoart #sciart I've been trying to learn more about graptolites as of late and for my first piece in a while, I chose to draw the large graptolite Pterograptus scanicus.

A large, winglike graptolite Pterograptus scanicus, floats in dark water. The right side is closer to the camera and illuminated by light, while the left side fades into the darkness. There are a regular series of glowing cyan lights along the branch-like 'feathers' of the graptolite. Close to the camera, a gray, transparent larval Caryocaris (a genus of phyllocarid) is ensnared in the graptolite's tentacles.

More ancient chelicerates for #InverteFest! These are: Plesiosiro (Haptopoda), Goniotarbus (Phalangiotarbida), Pleophrynus (Trigonotarbida) and the still surviving hooded tick spider (Ricinulei), which were discovered in the fossil record first and only then also found in the wild.

Plesiosiro, an obscure arachnid from the carboniferous period.
Designed by me in 2011.
Structure based on a 48 by 48 unit grid.
This little critter caught my attention because of the segments split in half.

Goniotarbus, an obscure arachnid from the carboniferous period.
Designed by me in 2011.
Structure based on a 48 by 48 unit grid.
This model is no longer accurate,
The interpretative reference image I had used to produce this model is now out of date.

Pleophrynus, a Trigonotarbid from the carboniferous period.
Designed by me in 2020. The structure is based on a 64 by 64 unit diagonal grid.
I've had a Trigonotarbid in my sights for a long time as a subject but I was eyeing Palaeocharinus originally.
The complex segmentation of the abdomen was simultaneously what piqued my interest in the first place but a daunting task all the same, which hampered any progress.
Many years have passed and that dream model has yet to materialize.
Then one day a friend approached with an inquiry for a commission to recreate a different Trigonotarbid altogether and I jumped at the opportunity.
This is the result.
I'm still seeing opportunities for improvement but it really was the best I could do three years ago.

An origami model of a hooded tick spider.
Designed by me in 2011, based on a 48 by 48 unit grid.
These really are funky little oddballs.
I still have the struggle it was to try and find usable reference images in vivid memory.
Thankfully, if and when I deem this one is due for a redo, I'm going to have much better references to compare against. :)

A conference abstract by Satyanarayana, et al. describes trilobite fossils from the Late Triassic Lower Dharmaram Formation in Telangana. This discovery shows that trilobites DID in fact survive the end-Permian mass extinction and even entered freshwater niches in the wake of the extinction.

Image of a conference abstract. The abstract is titled First record of philipsiid trilobites (Proetida: Phillipsiidae) from the Upper Triassic of Telangana and reads:
Trilobites (Order Trilobita) were one of the most successful clades of the Paleozoic, with an estimated 20,541 valid species as of 2008 (Adrain, 2008) and undoubtedly many more that have been described in the years that followed. However, it is widely accepted that trilobites went extinct as part of the end-Permian mass extinction following a long period of decline from the middle Devonian (Lerosey-Aubril & Feist, 2012). Recent finds in the upper Triassic fluvio-lacustrine Lower Dharmaram Formation (Dasgupta, Bannerjee, and Ghosh, 2022) challenge this belief. Fragments of trilobite exoskeletons recovered from the Lower Dharmaram formation have been assigned to cf. Pseudophillipsia, suggesting both that phillipsiid trilobites survived the end-Permian mass extinction and that they moved into freshwater ecosystems.

A young female Caspian Tiger has led her cubs on their first swim, across an estuary channel on the edge of the Caspian Sea. Unfortunately, a particularly massive Beluga Sturgeon has crossed their path, and it’s no stranger to hunting surface-swimming prey. #sciart #paleoart #wildlife #caspiansea

The tigress is leading her cubs in swimming across an estuary channel, with tall reeds lining the shores to the left and to the right. The sturgeon is curling its body upwards with its face pointing at the surface, mouth fully extended and in the process of sucking one of the cubs under the surface. A school of small trout are swimming under the sturgeon, while a heron stands along the distant shoreline of reeds and two Garganey Ducks fly overhead. The sky is clear, while the waters are gently shaded (light near the surface, darker near the bottom).
