Our first follow up from the Science paper: New paper on tooth morphology in the Grippia Bonebed - the oldest and most diverse Mesozoic marine tetrapod ecosystem. Paper open access here: njg.geologi.no/publications...
Dental and Dietary Disparity Among Marine Vertebrates from the Early Triassic (Spathian) of Svalbard – Life Bites the Dust, or A New Hope? - Norwegian Journal of Geology
The Early Triassic saw the recovery of ecosystems after the most severe mass extinction event in Earth’s history. However, the ecosystems of the Early Triassic and their patterns of recovery after the Permian-Triassic mass extinction are poorly known due to a scarce fossil record. This study uses dental material to provide information on the taxonomic […]

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.

anyway, a new and incredibly detailed study has been released about the ever-famous dunkleosteus, suggesting that it was a macropredatory generalist rather than the ammonoid specialist it is often portrayed as
(art by @literallymiguel.bsky.social)

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

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.

Danke @vonmallinckrodt.bsky.social fürs Finden
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

Biogeography after #Permian #Triassic boundary crisis resulted from a complex combination of functional and dispersal mechanisms doi.org/10.18261/let...

#Ammonoids limited by #dispersal in Griesbachian/Spathian, by niche in Smithian; #conodonts by #niche in Griesbachian, mixed in Dienerian–Spathian
Fig. 1. Palaeo-location of the 27 regions of A) conodont and B) ammonoid taxa taxa defined in this study, respectively. Each region is associated to its number of sampled localities encircled by five arcs, each arc corresponding to a time interval (Changhsingian, Griesbachian, Dienerian, Smithian, or Spathian). A coloured arc means that the region includes at least one locality dated from this time interval; an unfilled arc means that the region does not include any locality dated from this time interval. See the section Material and methods for details about the calculation of the palaeocoordinates. Silhouettes of conodont and ammonoid are public-domain images from the Phylopic website (compare https://doi.org/10.18261/let.58.3.2). Values of Dispersal-Niche Continuum Index (DNCI) show ammonoid biogeography was dispersal-constrained in Griensbachian and Spathian as opposed to niche constrained in the Smithian, while conodonts were more functionally (niche) constrained in Griesbachian as opposed to driven by both niche and dispersal constraints from the Dienerian to Spathian. Black dots and associated horizontal black lines represent mean value and ±2 standard error, respectively.
