Baltileuctra dewalti Chen sp. nov., a new extinct species of needle stoneflies (Leuctridae, Plecoptera), is described and illustrated from the Eocene Baltic amber and compared to the other leuctrids. Baltileuctra dewalti Chen sp. nov. differs from both extant and extinct representatives of Leuctridae by a combination of morphological characters including wing venation, unique terminalia structures, and cercal modification. The most distinguishable character for the new taxon is the presence of two dentate long spines lateral to a well-developed subanal probe. Several parasitic mites are also found on the new stonefly. This is the earliest known fossil evidence for mite parasitism in Plecoptera. This study examines a well-preserved piece of Eocene Baltic amber and discovers a new needle stonefly as the second known species of Baltileuctra which is parasitized by mites. New infor-mation is provided for Baltileuctra foraminis Chen, 2018a, and Euroleuctra gillesi Chen, 2018b, for morphological comparison.

The article presents an analysis of the names and logotypes of companies, associations and other organiza-tions operating for the benefit of the d/Deaf in Poland. The analysis concerns the relationship between the name (its meaning) and the way of identifying the community of d/Deaf people. The description covers both the names and graphic elements, and their symbolism, which are present in the logotypes. The findings of cognitive methodology are used to read the correlation between the name, its logotype and the values identi-fied with the d/Deaf. The analysis covers 50 social chrematonims and logotypes of institutions from Poland who promote their activities on the Facebook social network or on Polish websites. The material collected allows one to notice that the most common way of identification with the d/Deaf community is the use of meanings and symbols of Polish Sign Language (PJM), which is one of the most important values creating the image of the Deaf as a linguistic and cultural minority.

The article presents and characterizes the Latin vocabulary relating to the comet, used by the Polish writ-ers of the Middle Ages. Texts with descriptions or mentions of comets can be divided into two groups. The first includes astronomical and astrological works, the second chronicles and annals. Ambiguous and syn-onymous terminology reflects the writers’ level of knowledge, quality of sources, and personal interests. It should be emphasized that comets were rarely described objectively: they were often assigned supernatural meanings, and their names were the result of a specific perspective and interpretation.

We describe the anatomy of a new longirostrine pliosaurid, Eardasaurus powelli gen. et sp. nov., based on a substantially complete skeleton from the Middle Jurassic Oxford Clay Formation of Oxfordshire, UK. The specimen brings the number of pliosaurid genera known from the Oxford Clay Formation up to a minimum of six, contributing to our understanding of the most taxonomically rich pliosaurid assemblage. The teeth of Eardasaurus powelli gen. et sp. nov. have “carina-like” apicobasal enamel ridges, previously only identified in Liopleurodon ferox among Middle Jurassic pliosaurids, and which may be more widespread among early pliosaurids than has been recognised. Our phylogenetic analysis shows that Eardasaurus powelli gen. et sp. nov. is nested within Middle Jurassic thalassophonean pliosaurids, slightly more derived than Peloneustes philarchus , as sister to a group comprising “ Pliosaurus ” andrewsi , Simolestes vorax , Liopleurodon ferox , Pliosaurus spp. and brachauchenines.
我们描述了一种新的长颈上龙，Eardasaurus powelli gen. et sp. nov.，基于英国牛津郡中侏罗世牛津粘土组的基本完整骨架。该标本使牛津粘土组已知的上龙属数量至少达到6个，有助于我们了解分类最丰富的上龙组合。波利耳达龙(Eardasaurus powelli gen. et sp. 11 .)的牙齿具有“隆状”的尖基底牙釉质脊，这种牙釉质脊以前只在中侏罗世上龙中发现过，可能在早期上龙中更为普遍。我们的系统发育分析表明，Eardasaurus powelli gen. et sp. 11 .嵌套在中侏罗世thalassophonean pliosaurids中，与Peloneustes philarchus的衍生性略高，是由andrewsi“Pliosaurus”、Simolestes vorax、Liopleurodon ferox、Pliosaurus spp.和brachachenines组成的一个类群的姐妹。

A second specimen of the Australian cimolodontan multituberculate Corriebaatar marywaltersae from the same locality (Flat Rocks) as the holotype and previously only known specimen, reveals far more anatomical information about the species. The new specimen, composed of most of a dentary containing a complete p4 and alveoli for the lower incisor and the lower first and second molars, exhibits a suite of features consistent with allocation of Corriebaatar to Cimolodonta and further confirms the presence of multituberculates on Gondwana during the Mesozoic. The revised (older) age of the Flat Rocks locality to latest Barremian (mid-Early Cretaceous) establishes C. marywaltersae as the oldest currently known cimolodontan. This has profound biogeographic implications for the distribution of multituberculates on Gondwana as well as globally, particularly in light of the fact that Corriebaatar appears to be a relatively derived member of Cimolodonta.

Understanding the phylogenetic relationship among derived blastozoans has been a goal of researchers since phylogenetic methodologies were first applied to Paleozoic echinoderms. Paul (2021) proposed a new “pan-dichoporites” group to circumscribe early Paleozoic blastozoans. Unfortunately, this work includes many inaccuracies, non-reproducible analyses, and nonstandard method choices that confuse rather than advance the understanding of echinoderm paleobiology. Herein, we focus on key aspects of philosophy, methodology, and data reproducibility the publication of Paul (2021) raises that need to be addressed and considered by echinoderm researchers as they assess the concept of pan-dichoporite echinoderms.

A new genus of chemosymbiotic vesicomyid bivalve from the Oligocene of western North Palaeontologica 67 (X): xxx–xxx. We describe a new genus of the chemosymbiotic bivalve family Vesicomyidae, Squiresica , for two Oligocene species, previously assigned to Archivesica , from western North America. Squiresica is characterized by a small and weakly inflated shell, a small to nearly absent pallial sinus, an Archivesica -like hinge dentition, with an indistinct to well incised lunular incision. Two species are assigned to this new genus: the type species, S. knapptonensis from western Washington State, USA, and S. marincovichi from Oligocene strata of Alaska, USA. Squiresica knapptonensis had previously been described from the upper Oligocene of the Lincoln Creek Formation; further specimens are here reported from a newly discovered seep deposit in the lower Oligocene part of the Lincoln Creek Formation.
