The evolutionary convergence of mid-Mesozoic lacewings and Cenozoic butterflies
Mid-Mesozoic kalligrammatid lacewings (Neuroptera) entered the fossil record 165 million years ago (Ma) and disappeared 45 Ma later. Extant papilionoid butterflies (Lepidoptera) probably originated 80-70 Ma, long after kalligrammatids became extinct. Although poor preservation of kalligrammatid fossils previously prevented their detailed morphological and ecological characterization, we examine...
متن کاملCenozoic Soldiers Pass Volcanic Field, Central Utah—implications for the Transition to Extension-related Magmatism in the Basin and Range Province
The Basin and Range Province of the western United States is one of Earth’s most studied regions of continental rifting, and yet the timing and character of the onset of Cenozoic extension are still controversial. Some structural studies have concluded that extension in the Great Basin part of the Basin and Range Province is as old as 41–37 Ma (Rahl and others, 2002) or 32–30 Ma (e.g., Axen and...
متن کاملCenozoic basin development and stratigraphy of the Faroes area
The present paper reviews the geological development of the Faroes part of the NE Atlantic Margin in the Cenozoic Era. The Faroes area is located west of the post-Caledonian rift basin system formed in the Devonian after the collapse of the Caledonian mountains. Tectonic movements and plate reorganizations during several phases have strongly influenced sedimentation and erosion along the Caledo...

متن کاملRecycled crust controls contrasting source compositions of Mesozoic and Cenozoic basalts in the North China Craton
We explore Fe/Mn and Nb/Ta ratios of basalts as potential tracers for differentiating melts of recycled mafic crustal lithologies from peridotitic melts. Trace elements and Fe/Mn ratios of the Mesozoic and Cenozoic basalts from East China were analyzed by ICP-MS. Low Nb/Ta ratios (15.4 ± 0.3 (2r, n = 45)), high Nb and Ta contents (60.1 and 4.01 ppm) and high Fe/ Mn ratios (64.7 ± 1.5 (2r, n = 4...
