The Anatomical Record, EarlyView.Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Stratigraphy of the Miocene Series in the Hiki Hills, Saitama Prefecture, central Japan
The Journal of the Geological Society of Japan, 2004 埼玉県比企丘陵と岩殿丘陵の間にわずかに露出する海成中新統より, Denticulopsis lauta帯を示す珪藻化石が産出した. 新たに得られた珪藻化石年代と既存の報告を総括し, 比企丘陵の岩相層序を年代層序に基づいて整理した. その結果, 15.4 Maを境にして下位の珪藻質シルト岩からなる荒川層と, 上位の砂質シルト岩からなり不淘汰角礫岩や砂質シルト岩さらに砂質シルト岩の同時礫を取り込む海底地滑り堆積物からなる市ノ川層に二分されることが判明した. 新たに得られたT-3凝灰岩 (畠山凝灰岩) のフィッショントラック年代は上記年代層序と矛盾しない.

7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia
Archaeology in Oceania, EarlyView.ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

Deep Underground Science and Engineering, EarlyView.This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Deep Underground Science and Engineering, EarlyView.This paper presents temporal and adaptive‐frequency network with MixStyle (TAMNet), a deep time‐series modeling framework for accurate and robust multi‐well oil productivity forecasting. TAMNet integrates transformer and long short‐term memory architectures to capture both short‐ and long‐term temporal dependencies, enhanced by a temporal gate unit ...
