Trilobiten aus dem Unter-Karbon des Katalonischen Küstengebirges (NE-Spanien)
2015, 83 S., 40 Abb., 2 Tab., 10 Tafeln
ISBN 978–3–510–61403–5, paperback, € 24,90

Aus 4 Lokalitäten des Katalonischen Küstengebirges (NE-Spanien), nämlich Aiguafreda, Cànoves, Papiol und Scala Deï werden insgesamt 18 Trilobiten- (Unter-) Arten der Proetidae-Unterfamilien Drevermanniinae, Cyrtosymbolinae und Mirabolinae beschrieben. Eine Gattung, 4 Untergattungen und 16 (Unter-) Arten, davon 15 voll benannt, sind neu beschrieben.
Als Folge zeichnen sich zunächst zwei nahe beieinander liegende Zeithorizonte ab. In den ersten drei der vier Lokalitäten entstammen die Trilobiten der „Formación El Papiol“, deren Fazies und Fauna auch an der N-Küste von Menorca vorkommt. Durch den Faunenvergleich mit dieser Insel und einigen Conodonten der bilineatus-Zone wird schließlich ein tieferes Ober-Visé Alter, etwa Go α4/?#946;str, wahrscheinlich. So gut wie alle Trilobiten sind blind oder fast blind und zeigen einen überaus flachen Körperbau. Sie werden zudem von einer benthonischen „Kümmerfauna“ begleitet, was auf ein Leben am Boden eines tieferen Schelfs schließen lässt und auf die Fähigkeit, sich im schlammigen Sediment einzugraben.

Fossil Fruits and Seeds of the Middle Eocene Messel biota, Germany
2012, 251 pp, 2 figs, 3 tabs, 76 plates
ISBN 978–3–510–61400–4, paperback, € 49.80

The oil shale of the Middle Eocene Messel Formation as exposed in the Messel Pit near Darmstadt, Hessen, Germany, is a famous and widely known source for extremely well preserved fossils documenting a wealth of terrestrial biota. For this reason the Messel Pit Fossil Site was awarded the status of a UNESCO World Heritage Site documenting the ecosystem on the European mainland which existed under a paratropical climate during Paleogene greenhouse conditions.
A survey of the extensive fruit and seed collections from the Middle Eocene oil shale of the Messel Formation now reveals at least 140 genera, representing more than 34 families of seed plants. The flora includes occasional conifer and numerous angiosperm remains. There are 34 extant angiosperm families represented of which ten are new records for Messel, plus 65 morphotypes of unknown familial affinity. Three extant genera are recorded for the first time from the Paleogene. The assemblage indicates a wide range of dispersal strategies including pods, capsules, explosive dehiscence, a single arillate seed, two seed-types with dispersal hairs and most modern categories of winged disseminules. In terms of mammalian frugivory the flora contains examples of all potential dietary categories. Tough and hard materials are abundant and soft material is common. Gut contents preserved in many birds and mammals prove that fruits and seeds played an integral part in vertebrate diets and borings in one seed type indicate seed predation by weevils. Previous quantitative studies suggesting an equable warm and humid palaeoclimate with some seasonality for Messel are supported by the newly recognised taxa. Judging from the habit of related living taxa, the vegetation appears to have been a multilevel canopy forest, including a high proportion of lianas in addition to shrubby to arborescent taxa. Herbaceous components are also present but relatively underrepresented. Among other large and well-studied Eocene macrofloras, the Messel assemblage shows overlap with the genera known from the London Clay flora of England and the Clarno Nut Beds Flora of Oregon, but relatively little similarity with floras known from eastern Asia. Compared with extant floras, the Messel flora includes a temperate component with mostly Asian endemics, and some genera that are now disjunctly distributed in the Northern Hemisphere. A large tropical-paratropical component includes genera now confined to the Old World tropics, particularly southeastern Asia and Malaysia, but there are also a few exclusively Neotropical elements.
Altogether, the Messel flora can be regarded as one of the most diverse Paleogene floras worldwide.

Die Karbon-Trilobiten des Kantabrischen Gebirges (NW-Spanien), 5: Trilobiten des höheren Westfal

(in german)

This paper is the fifth part of a comprehensive study, dealing with the Carboniferous trilobites of the Cantabrian Mountains. Trilobites are described from more than 90 different localities. With the exception of two localities of Westphalian A (Langsettian) age and a few ones corresponding to the lower Cantabrian substage of the basal Stephanian, they all belong to the Westphalian C (Bolsovian) or D (Asturian), thus following closely upon the late Namurian and early Westphalian trilobites described in 1987. The localities involved mainly occur in 4 principal areas, viz (1) the region of the “Manto del Ponga”, east of the Central Asturian coalfield (province of Oviedo); (2) the area around the “Puerto del Pando” (province of León); (3) the Casavegas Syncline (province of Palencia); and (4) the southern flank of the Castillería Syncline (province of Palencia). Additionally, an upper Westphalian trilobite locality is recorded from the Sierra de la Demanda (at Valmala, province of Burgos) for the first time.
Most of the localities are dated quite precisely, with reference to brachiopods, foraminifera (Fusulinacea) and/or land plants, and are situated in well-studied sections. On the other hand, it has been possible to propose certain correlations by means of trilobites with a higher degree of precision than it had been feasible previously.

Bryozoan fauna and microfacies from a Middle Devonian reef complex (Western Sahara, Morocco)
2010, 91 pp., 6 figs, 1 tab., 27 plates, 1 app.,
ISBN 978–3–510–61397–7, paperback,  € 24.80

Devonian bryozoans from North Africa are scarcely known. The present study is devoted to the investigation of bryozoan fauna and microfacies of a Middle Devonian reef complex in Western Sahara, Morocco. In total, 26 bryozoan species were identifi ed. Two genera with two species are new: Lenapora pulchra n. g. n. sp. and Dissotrypa sincera n. g. n. sp. Furthermore, 15 new species were described: Fistuliphragma parva n. sp., Sulcoretepora moderata sp. n., Leioclema crassiparietum n. sp., Eridotrypella minutiformis n. sp., E. modesta n. sp., Atactotoechus gaetulus n. sp., Acanthostictoporella angusta n. sp., Euspilopora spinigera n. sp., Acanthoclema triangularis n. sp., Rhombopora minutula n. sp., Prolixicella lata n. sp., Rhombocladia striata n. sp., Filites gaetulus n. sp., Anastomopora clara n. sp., and A. recta n. sp. Four species are described in open nomenclature: Spinofenestella sp., Hemitrypa sp., Ptylopora sp., and Semicscinium sp. The studied fauna shows relations to the Middle Devonian of Holy Cross Mountains, Poland and Rhenish Massif, Germany, as well as to the Middle Devonian of North America.

The glass frog tadpoles of Costa Rica (Anura: Centrolenidae): A study of morphology
2010, 78 pp., 142 figs, 14 tabs.,
ISBN 978–3–510–61396–0, paperback, € 32.80

Larvae of the neotropical frog family Centrolenidae live hidden on the bottom of rivers between stones, gravel, and leaf litter. Their lotic fossorial behavior makes it impossible to find and study these tadpoles in their natural environment. Therefore, presently only poor reports and descriptions of them are available in the literature.

In the present study all known 13 Costa Rican centrolenid species (or taxa) were reared under laboratory conditions. Their live tadpoles are described in different stages of their development. Six of the 13 descriptions are new (Cochranella euknemos, Sachatamia albomaculata, Sachatamia ilex, Hyalinobatrachium chirripoi, Hyalinobatrachium talamancae and Hyalinobatrachium vireovittatum). A species key and detailed diagnostic descriptions with abundant illustrations allow the identification of tadpoles of the thirteen species.
