Yeah, but on the other hand the former pronunciation might also be WP:RS too, so keeping both out of the article might be clever

Prehistoric Soundscapes Exhibit November 18 - November 26, 2024 - Como Zoo Conservatory Step into Como’s Fern Room and prepare for a journey back 75 million years! Stroll through a prehistoric soundscape filled with calls from dinosaurs and creatures that once roamed ancient...

Are you in the Twin Cities and wonder what dinosaurs sounded like? Come check out our exhibit at Como Conservatory where we used an instrument based on hadrosaur skulls to create an immersive soundscape in the Fern Room! Nov 18th-26th! #Hadrophone

The last paper, finally, by Kuzmin, goes over the presence of Benthosaurus (now Benthosuchus), Wetlugasaurus and Capitosaurus in Permo-Triassic deposits of the Oka-Znin Anticline, in European Russia. (Illustration 1 and 3 by D. Bogdanov, 2 by Plioart)

The penultimate paper in the issue, by Slodkevich, describes three fragmentary skull remains assigned to Cuon alpinus europaeus, the European dhole, from Nizhneudinskaya Cave.

the following paper, by Ryabinin, reports the discovery of a single caudal vertebra of the cave lion, Panthera spelaea, in Middle Pleistocene deposits near Astana, Kazakhstan, in a locality also bearing remains of wooly mammoths and Eurasian castors.

Next paper, by Pavlova, reports the discovery of a giraffe skull assigned to Camelopardalis parva in Miocene age rocks of the Northern Caucasus (now, to my understanding, either Bohlinia attica or Palaeotragus rouenii).

The following paper, by Orlov, covers in great details the affinities of Semantor macrurus with modern pinnipeds and the musculature of its hindlimbs. The illustrations, made for the paper, were created by A. P. Bystrov.

...as well as P. watsoni (art by Dylan Bogdanov) and Melosaurus sp. (art by @joschuaknuppe.bsky.social)

Next paper, by Efremov, covers the presence of Late Permian temnospondyls along tributaries of the Viatka River in Russia. Efremov reports the presence there of the archegosaur Platyops (now Platyoposaurus) stuckenbergi (Art by Sergey Krasovskiy)...

and two new genera, Gyroplacosteus (G. panderi and G. butovi) and Megaloplax (M. marginalis).

Next paper, by Obruchev, covers Holonemid placoderms of the USSR. The author describes a new species of Holonema from the Late Devonian of St Petersburg, H. radiatum...

(Reconstruction by Andrey Atuchin)

and Permocupidae (Permocupes semenovi and Permocupoides distinctus nov. gen. et spe.)
And this conclude this extremely long insect description part !

Finally, coleopterans are represented by Protocoleidae (Arctocoleus ivensis nov. gen. et spe.), Permosynidae (Permocrossos elongatus nov. gen. et spe.), Sojanocoleidae (Sojanocoleus reticulatus nov. gen. et spe.)...

Still in neuropterans, the new family Permosisyridae (now Permithonidae) is represented by the new genus Permosisyra (P. latipennis and P. punctata) ;
For Megalopterans, Permosialidae are represented by P. bifasciata and Archisialidae by the new genus Archisialis (A. praecox)

Part II of the article by Martynov covers other insects found in the same localities of Arkh. Oblast.
Palaeomerobiid neuropterans are represented in Iva-Gora by the new species Permegalomus maculipennis, and the new genera Permithonopsis (P. ivensis and P. proxima) and Eopsychops (E. sojanensis)

... describes a quite well preserved specimen from Iva-Gora as a new species of Kamopanorpa, K. rotundipennis, and a single wing from the same locality as the type of a new genus, Permocentropus philopotamoides, itself within a new family, Permocentropidae !

... two specimen of Permopanorpa from Iva-Gora become the holotype for P. angustata and P. tenuis, respectively ; he refers two new species, P. distincta (Iva-Gora) and P. dubia (Iva-Gora) to Petrochorista...

- P.(?) stigmata (Iva-Gora)
- P. sp. (Iva-Gora)
- P.(?) dubiosa (Iva-Gora)
He also refers a specimen of Parachorista from Iva-Gora as P. opposita...

He also refers several new specimens to new species of Permochorista :
- P. maculipennis (Iva-Gora) and its variety P. maculipennis var. major (Iva-Gora)
- P. nigromaculata (Iva-Gora)
- P. venosa (Iva-Gora)

He establishes the genus Oochorista with its type, O. gunderseni, from Iva-Gora ; refers several specimens from both sites to Petromantis borealis and establishes two new species, P. punctata (Iva-Gora, unillustrated) and P. robusta (from both sites)

A. splendida (Iva-Gora, Sheimo-Gora) ;
A. dubia (Iva-Gora) ;
A. reducta (Iva-Gora) ;
...

A. sp. (Iva-Gora) ;
A. umbrata (Iva-Gora) ;
A. fasciata (Iva-Gora) ;
...

Next, Martynov (part I). This section covers the description of several mecopteran species from Permian layers in Arkhangelsk Oblast.
He starts with the new Mesochoristidae (now Permochoristidae) genus Agetochorista, to which he describes many species :
Agetochorista ornata (Sheimo-Gora, Iva-Gora)

Next comes Popov ! The paper describes two new species of Miocene Formicid ants : Ponera(?) umbra, from Kurganskij, Krasnodar Oblast (left), and Lasius martynovi, from Ormety, Georgia. (right)

Let's start with Fedotov ! The author assess variability in the modern Chlamys islandica (the Iceland scallop) to serve as a scale for assessing the novelty of fossil species.

- Ryabinin, Note on the vertebra of a cave lion from the Quaternary deposits of Western Siberia
- Slodkevich, Remains of Cuon from Quaternary deposits of Nizhneudinskaya
- Kuzmin, Locations of labyrinthodonts in the variegated layer of the northern part of the Oka-Tsna ridge

- Efremov, Permian labyrinthodonts from the former Vyatka province
- Orlov, Semantor macrurus, a representative of a new family of pinnipeds
- Pavlova, Camelopardalis parva Weith. from Sarmatian deposits of the Caucasus
...

Starting with the index :

- Fedotov, On the variability of modern pelecypods in connection with the study of fossil forms
- Popov, Two new fossil ants from the Caucasus
- Martynov, Permian fossil insects of the Arkhangelsk region (I and II)
- Obruchev, Holonemidae of the Russian Devonian
...

Welcome to this second entry ! Following with "Acts of the Institute of Paleozoology", t. 2, 1933.

To the program today : Insects galore, "labyrinthodonts", stem-pinnipeds and Caucasian giraffes ! #paleo #paleoart

Have some feels good paleoart in these trying times
