Pondweed bugs (Hemiptera: Mesoveliidae), considered a sister group to all other Gerromorpha, are exceedingly rare as fossils. Therefore, each new discovery of a fossil mesoveliid is of high interest, giving new insight into their early evolutionary history and diversity and enabling the testing of their proposed relationships. Here, we report the discovery of new mesoveliid material from Spanis...

The studies were carried out on 93 samples of cuttings from the K1 oil well. These processed using Fluorescence Spectrometer (XRF) method. Chemical analyses contributed to determination depositional environments and origin sediments. Albian sediments deposited in an environment proximal continental characterize MS1 mega-sequence. In contrast, MS2 mega-sequence (Cenomanian Maastrichtian) was a s...
