The critical importance of public and up-to-date, expert-vetted ...
The database is vital for studying Permian–Triassic stratigraphy, diversity, and evolution—and it spotlights the broader need to fund taxonomic expertise, collect new data, integrate scattered resources, and build sustainable, accessible, community-driven infrastructure. doi.org/10.1017/pab....

Large databases depend on taxonomic foundations that are often under-cited. hal.science/hal-04951445 include all 260 source publications and show how expert cleaning reduces species counts by half—reinforcing how crucial taxonomic rigor is for reliable deep-time biodiversity metrics.

Evolution of the taxonomic richness of Late Permian-Early Triassic conodonts comparing the present database and the PaleoBiology Database (PBDB). The metric used here is the raw counting (sample in bin) of conodont species. PBDB data extracted with the R package PaleoDiv (Nau 2025) on 06/25/2025 and the raw data are available on the GitHub repository in the folder Datapaper_PCI Paleo. The time scale was built with divDyn R package (Kocsis et al. 2019) but the absolute ages are from Leu et al. (2025). Abbreviations: Gr – Griesbachian; Di – Dienerian. https://hal.science/hal-04951445v5
Up-to-date data reshape our understanding. For the Permian–Triassic, the new vetted dataset (hal.science/hal-04951445v5) shows diversity trends that differ sharply from PBDB, highlighting how exhaustive, expert-curated compilations can dramatically change interpretations of extinction and recovery.

A database of conodont occurrences between the Changhsingian (Late Permian) and the Spathian (Olenekian, Early Triassic)
We introduce here a database of global occurrences of conodont species around the Permian/Triassic boundary (PTB, ca. 251.9 Ma). The PTB is known for its biotic crisis, i.e. the most important mass extinction event of the whole Phanerozoic, which profoundly impacted the marine biosphere and was followed by a complex biotic recovery during the whole Early Triassic Epoch (ca. 5 myrs). The PTB crisis has been extensively studied and conodonts survived to it but their evolution around the PTB was barely studied quantitatively. We provide here the most complete database of conodont occurrences in the latest Permian and the Early Triassic. It is a data compilation from the available literature, a csv file of about 12,000 entries, gathering a total of 260 publications dated from 1967 to 2022. The database includes taxonomic, sampling, sedimentological, temporal, (paleo)geographical and bibliographical information. The minimum unit, i.e. a row in the table, corresponds to a conodont species in a sample. The temporal resolution is the stage and substage, ranging from the Changhsingian (Late Permian) to the end of the Spathian (Olenekian, Early Triassic). The database allows a large range of investigations such as diversity, biogeographic, macroecological and biochronological studies that can be investigated at different geographic scale thanks to the GPS coordinates associated to each occurrence. The database can be downloaded and used freely as far as this associated datapaper is cited in any resulting publication. It will be updated once a year with new publications and taxonomic updates.
hal.science/hal-04951445 compiled ~12,000 conodont entries from 260 publications across four continents—an expertly vetted dataset enabling high-resolution diversity, biogeographic, biochronologic, and macroecological analyses, with plans for annual updates.

The critical importance of public and up-to-date, expert-vetted ...
Conodont research faces the same challenges: these tiny vertebrates are vital for biostratigraphy, paleotemperature studies, biodiversity work, and extinction research. Their record is key to understanding crises across the Permian–Triassic, including the end-Permian and Smithian events.

The taxonomic impediment: a shortage of taxonomists, not the lack of technical approaches
For almost 30 years, there have been active discussions about the taxonomic impediment and the challenge this represents to address the current human-induc
High-quality paleontological datasets take years to assemble. They require fieldwork, curation, expert taxonomic study, and major resource investment. Despite tech advances, funding for this foundational work is shrinking (doi.org/10.1093/zool...) —even though tech can’t replace taxonomic expertise.

Fossils for Future: the billion-dollar case for paleontology’s digital infrastructure
Public digital infrastructure (doi.org/10.32942/X2D...) has transformed our analyses, but its value depends entirely on data quality. PBDB remains central, yet cleaning and vetting data is still essential—especially as new resources like the Late Permian–Early Triassic conodont dataset emerge.

Figure 1 from a paper published in Nature (linked in post). The figure purports to be an infographic depiction of the "Overall working of the framework" for 'explainably' diagnosing autism spectrum disorder. The infographic is plainly nonsense, containing many spelling errors, nonsense words, meaningless images and graphs. Clearly created using generative AI and (crucially) NEVER CHECKED AT ANY STEP OF THE WRITING OR PUBLICATION PROCESS.
Hey @nature.com, have you got an explanation for how the hell THIS happened? & especially why you accepted a paper with such a bizarre piece of genAI slop in it?!
& more to the point, why we should take you seriously at all going forward?

Oil painting of two nautili and one allonautilus on a blue gradient background with patches of copper mica. Each cephalopod has an atomic diagram around it like a halo.
Have you ever heard of an allonautilus? The fuzzy sea peach at the top of my oil painting is the extremely rare allonautlius. Its only been documented in the wild a couple of times.

miguel's "scawwy" dunkleosteus that lacks labial tissue; actually found to be the more accurate despite his other version being considered 'accurate' at the time! it has a grainy, analog-horror esque filter over the image

Bildbeschreibung (Deutsch)
Die Grafik zeigt vier Panels, in denen jeweils eine Baumgruppe unterschiedlichen Naturgewalten ausgesetzt ist.
• Huracán (Hurrikan): Die Bäume biegen sich stark im Wind, bleiben aber stehen.
• Tsunami: Die Bäume stehen im steigenden Wasser, einige Äste treiben im Wasser, doch der Wald existiert.
• Terremoto (Erdbeben): Die Bäume wackeln heftig, Vögel fliegen auf, aber sie bleiben verwurzelt.
• Neoliberalismo: Das letzte Panel zeigt eine kahle Fläche. Keine Bäume mehr, nur noch abgesägte
Stümpfe.
Die Botschaft: Naturkatastrophen können Bäume erschüttern - aber systemische Ausbeutung zerstört einen Wald vollständig
Nichts zerstört die Natur so sehr wie #Neoliberalismus. Ausbeutung der natürlichen Ressourcen der Welt, zum Vorteil einiger Wenigen und zum verheerenden Nachteil der sehr vielen Anderen.
Ich finde das Bild sehr anschaulich.
