“…Bose & Manum. These genera were described from the early Jurassic to Early Cretaceous of several circum‐Arctic localities (Bose, ; Bose & Manum, , ), north‐western Germany (Manum, Van Konijnenburg‐Van Cittert & Wilde, ), western Kazakhstan (Nosova & Kiritchkova, ) and the Iberian Peninsula (Gomez, ). These sciadopitoid genera were transferred into the new family Miroviaceae, together with the genus Tritaenia Mägdefrau & Rudolf (Bose & Manum, ; Manum et al ., ).…”

“…Sciadopityoides Sveshnikova, Mirovia Reymanówna emend. Bose & Manum) show features which are not present in the amber fossils, particularly the entire acute, obtuse or acuminate apices, but also different ‘needle’ shapes, a hole in the leaf bottom or tuberculate papillae (Bose & Manum, , ; Gomez, ). In addition, the known stratigraphic range of Miroviaceae, extending from the middle Jurassic to the Early Cretaceous (Bose & Manum, ), makes it rather unlikely that the late Eocene amber fossils are affiliated with this family.…”

Sciadopityscladodes from Eocene Baltic amber

et al. 2015

The Baltic amber deposit represents the largest accumulation of any fossil resin worldwide and hundreds of thousands of entrapped arthropods have been recovered so far. The source plants of Baltic amber, however, are still controversial, and the botanical composition of the 'Baltic amber forest' remains poorly studied. Here, we provide the first unequivocal Baltic amber inclusions of the umbrella pine Sciadopitys (Sciadopityaceae), a genus that has been suggested as the source of succinite (the main variety of Baltic amber) based on chemical analyses. As previously suggested sciadopitoid inclusions must be reconsidered as being notional, representing angiosperm leaves instead, the new fossils are the first unambiguous macrofossil evidence of Sciadopitys from the 'Baltic amber forest', and the first pre-Oligocene macrofossil record of Sciadopitys from Europe. The fossil Sciadopitys cladodes provide new insights into the conifer diversity of the 'Baltic amber forest' and broaden the picture of its palaeoecology, indicating the presence of humid swamp to raised bog habitats.

“…Now these genera are placed in the Miroviaceae M.N.boSe et ManuM, which are distinguished from Sciadopitys by the absence of an emarginate tip and two veins (Bose andManum 1991, Manum et al 2000). These taxa originate from circum-Arctic localities (Halle 1915, Florin 1922, Bose 1955, Gothan and Weyland 1973, Bose and Manum 1990, Poland (Reymanówna 1985, Nosova andWcisło-Luraniec 2007), Germany (Manum et al 2000), Spain (Gomez 2002) and Kazakhstan (Nosova and Kiritchkova 2008). The exact relationship of the Miroviaceae to Sciadopitys remains uncertain.…”

The occurrence of pollen of Sciadopityaceae Luerss. through time

Here we present LM and SEM data of pollen of extant Sciadopitys verticillata, fossil Cerebropollenites from Aptian/Albian strata (Austria, Mongolia) and Sciadopityspollenites from Campanian/Maastrichtian and Oligocene/Miocene strata (Siberia, Germany). Measurements and image comparisons show that the investigated fossil pollen taxa range from somewhat comparable to very similar to extant Sciadopitys verticillata, and that a previous affiliation of Cerebropollenites taxa with Tsuga cannot be corroborated. Additionally, it can be speculated that either the Rhaetian to Lower Cretaceous Cerebropollenites taxa are the pollen equivalent of the Eurasian Miroviaceae macrofossils that have unresolved relationships with Sciadopityaceae, or that they might belong to a basal group in the Sciadopityaceae, which is quite recognizable due to the similarity of the pollen morphology of Cerebropollenites thiergartii and Sciadopitys verticillata. However, until in situ pollen within cones attributed to the Miroviaceae are found, we will not know for sure.

“…The sandstone laterally shifts into dark siltstone to mudstone and heterolithic deposits with mud drapes and wavy to flaser laminations, showing similar characteristics to the heterolithic siltstone/mudstone described in the Cortes de Arenoso section ( Fig 5 ). Despite plant remains being common and evenly distributed throughout the succession, only the lower part of the section (interval between 20 to 27 m in Fig 6 ) was sampled and analysed in previous palaeobotanical studies [ 29 , 30 ]. Amber fragments are abundant [ 40 , 44 ] and recorded in a mudstone bed of the upper part of the succession, which is sharply overlain by the marine carbonates of the Mosqueruela Formation [ 47 ].…”

Biodiversity of ecosystems in an arid setting: The late Albian plant communities and associated biota from eastern Iberia

et al. 2023

Deserts are stressful environments where the living beings must acquire different strategies to survive due to the water stress conditions. From the late Albian to the early Cenomanian, the northern and eastern parts of Iberia were the location of the desert system represented by deposits assigned to the Utrillas Group, which bear abundant amber with numerous bioinclusions, including diverse arthropods and vertebrate remains. In the Maestrazgo Basin (E Spain), the late Albian to early Cenomanian sedimentary succession represents the most distal part of the desert system (fore-erg) that was characterised by an alternation of aeolian and shallow marine sedimentary environments in the proximity of the Western Tethys palaeo-coast, with rare to frequent dinoflagellate cysts. The terrestrial ecosystems from this area were biodiverse, and comprised plant communities whose fossils are associated with sedimentological indicators of aridity. The palynoflora dominated by wind-transported conifer pollen is interpreted to reflect various types of xerophytic woodlands from the hinterlands and the coastal settings. Therefore, fern and angiosperm communities abundantly grew in wet interdunes and coastal wetlands (temporary to semi-permanent freshwater/salt marshes and water bodies). In addition, the occurrence of low-diversity megafloral assemblages reflects the existence of coastal salt-influenced settings. The palaeobotanical study carried out in this paper which is an integrative work on palynology and palaeobotany, does not only allow the reconstruction of the vegetation that developed in the mid-Cretaceous fore-erg from the eastern Iberia, in addition, provides new biostratigraphic and palaeogeographic data considering the context of angiosperm radiation as well as the biota inferred in the amber-bearing outcrops of San Just, Arroyo de la Pascueta and La Hoya (within Cortes de Arenoso succesion). Importantly, the studied assemblages include Afropollis, Dichastopollenites, Cretacaeiporites together with pollen produced by Ephedraceae (known for its tolerance to arid conditions). The presence of these pollen grains, typical for northern Gondwana, associates the Iberian ecosystems with those characterising the mentioned region.
