“…3 and 4). Comparable compositions of polar biomarkers were hitherto reported only from much younger geological samples, namely, fossil plants, resins, and coals of Tertiary or Cretaceous ages (e.g., Grimalt et al 1988;Alonso et al 2000;Otto and Simoneit 2001;Otto et al 2002aOtto et al ,b, 2003Otto et al , 2005Stefanova et al 2002). Polar diterpenoids under discussion are surely derived from the fossil wood analyzed.…”

“…Polar terpenoids such as ferruginol, sugiol, and other phenolic diterpenoids were reported predominantly from Tertiary conifers, sediments, resinites, and lignites from different locations (e.g., Grimalt et al 1988;Stefanova et al 2002;Otto and Simoneit 2001;Otto et al 2002aOtto et al , 2003Otto et al , 2005. The oldest polar terpenoids are known from Cretaceous resinites (Alonso et al 2000) and a few Cretaceous gymnosperm remains, such as Sphenolepis (Otto et al 1999) and Tritaenia (Otto et al 2002b). In all these cases only minor amounts of ferruginol and other unaltered terpenoids were detected.…”

Biomarkers are widely known to occur in the fossil record, but the unaltered biomolecules are rarely reported from sediments older than Paleogene. Polar terpenoids, the natural products most resistant to degradation processes, were reported mainly from the Tertiary conifers, and the oldest known are Cretaceous in age. In this paper, we report the occurrence of relatively high concentrations of ferruginol derivatives and other polar diterpenoids, as well as their diagenetic products, in a conifer wood Protopodocarpoxylon from the Middle Jurassic of Poland. Thus, the natural product terpenoids reported in this paper are definitely the oldest polar biomolecules detected in geological samples. The extracted phenolic abietanes like ferruginol and its derivatives (6,7-dehydroferruginol, sugiol, 11,14-dioxopisiferic acid) are produced only by distinct conifer families (Cupressaceae s. l., Podocarpaceae and Araucariaceae), to which Protopodocarpoxylon could belong based on anatomical characteristics. Therefore, the natural product terpenoids are of great advantage in systematics of fossil plant remains older than Paleogene and lacking suitable anatomical preservation.

“…It is considered to be one of the most important Lower Cretaceous amber deposits in the world due to the high grade of the fossil resin, the number and quality of the preserved biological inclusions (Fig. 3), and its age (Upper Aptian according to Alonso et al 2000 or Upper AptianLower Albian age after Barrón et al 2001-depending on where the Aptian-Albian boundary is drawn).…”

“…The most represented inclusions belong to the Hexapoda, mainly to the class Insecta. These are representative of the orders Collembola, Thysanura, Blattodea, Psocoptera, Thysanoptera, Hemiptera, Neuroptera, Trichoptera, Lepidoptera, Diptera, Coleoptera, and Hymenoptera (Alonso et al 2000). The collection of amber bioinclusions from Peñacerrada contains thousands of specimens, all housed in the Museo de Ciencias Naturales de Álava (Natural Sciences Museum of Álava, Basque Country).…”

“…Later, it was considered as a Spanish geosite (under the name FC-10) within the context for Lower Cretaceous fossils and ichnofossils of the Iberian Peninsula (IGME 2008;Carcavilla et al 2009). Excavations were undertaken in 1995, 1997, and in 2000, an interdisciplinary group was created to define the geology and evolution in time of the deposit . However, the delicate nature of the first emergency excavations, as well as the discretion necessary to protect the deposit, did not allow topographic surveying of the extractions.…”

The Upper Aptian–Lower Albian Amber Deposit of the Peñacerrada II Geosite (Basque–Cantabrian Basin, Northern Spain): Geological Context and Protection

The conservation of the Peñacerrada Lower Cretaceous amber deposit has been possible thanks to scientific activity and administrative strategies. Since its discovery in 1994, it was declared as a cultural site in 1998, listed as a Spanish geosite in 2008, and has been scientifically excavated-and is duly protected. Once the context and geological evolution of the deposit had been established and protocols for the study, publication, and conservation of the extracted amber implemented, the question of whether to continue the systematic excavation of the site or to preserve it was raised. To answer this question, a detailed geometric a topographic analysis to evaluate the volume of preserved amber-bearing rock was undertaken and, ultimately, a conservation focused stance was proposed.

Manicapsocidus enigmaticus gen. n. sp. n. is described from some amber inclusions of the Cretaceous deposit of Alava (Northern Spain). It is provisionally placed into the extant family Manicapsocidae. This new species shares some features with the Compsocidae and possesses some unusual exclusive characteristics. The discovery of this new species will probably have a certain impact on the interpretation of the phylogeny of the Electrentomoid Psocoptera.
