A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

open access: yesJournal of Anatomy, Volume 249, Issue 5, Page 1021-1032, November 2026.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

On the Origin of the Tingidae (Insecta, Heteroptera)

open access: yesZoologica Scripta, Volume 55, Issue 6, Page 876-892, November 2026.
ABSTRACT The hypothesis of a Gondwanian origin of the family Tingidae (Insecta, Heteroptera) has been promoted and seems to be generally accepted by specialists. However, the area of emergence and diversification of the clade, South American or Australian, is still debated and cannot be solved without integrating Vianaidinae, a subfamily considered as ...

Position of the Lhasa Terrane and Two‐Stage Crustal Shortening During the India–Asia Collision

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The paleolatitudinal change of the Lhasa Terrane is critical for estimating the timing of the India–Asia collision and associated syn‐to post‐collisional crustal shortening, but its paleoposition is highly debated. Here we present integrated geochronologic and paleomagnetic results from the Lower Eocene Nianbo Formation in the Linzhou Basin ...
