Divergent defense strategies and niche partitioning in Cretaceous micro‐beetles
Journal of Systematics and Evolution, EarlyView.We report a new clambid beetle from mid‐Cretaceous Kachin amber, Scutacalyptus kolibaci gen. et sp. nov., characterized by a flattened body and explanate margins. Alongside spiny and conglobating clambid forms, this diversity reflects niche partitioning and varied antipredator strategies in the Cretaceous forest floor.

Long‐Term Storage of Meteoric Water in the Variscan Basement: Stable Isotope Constraints (δD–δ18O)
Terra Nova, EarlyView.ABSTRACT F‐Ba‐Pb‐Zn (±Ag) deposits near the unconformity between the Armorican and Aquitaine basins formed by mixing surface waters and brines with fluid ascending from the basement. To better constrain the source of this fluid and the conditions of mixing, we analyzed the hydrogen (δDwater) and oxygen (δ18Owater) isotopic composition of water trapped ...
