From the album: Fossils from the Plattenkalke of the Altmühl Valley
nice and not common fish from Eichstaett, seems to be Ophiopsis (little bit unsure about because of a fin and shape). Lenght is approx. 15 cm-

From the album: Fossils from the Plattenkalke of the Altmühl Valley
rare Coelacanth in unusual preservation. Seems to be Coccoderma, perhaps part of a meal. Fantastic skin preservation and good skull. Back part and tail got lost in the field, so I do not know how complete it was. Size is approx. 14 cm what you see. Was found in Eichstaett many years ago, comes from an old collection-

Taxonomy from Fossilworks.org. Etymology: Lepidota (Greek), a form of lepidotós, scaly. Grande & Bemis 1998, p.490: “ Originally described as †Megalurus lepidotus by Agassiz in 1833:146, and listed that way by numerous authors over the next 100 years or so, but †Megalurus Agassiz is a junior homonym--see generic list for †Amiopsis Kner, 1863, above. Also referred to as †Urocles lepidotus by Jordan (1919:567); Lange (1968:32); Lambers (1992:295); and others." Grande & Bemis 1998, p.493: “Emended species diagnosis-†Amiopsis lepidota differs from other species of the genus by the following adult characters A through D (note there is a range of overlap between some species for characters B, C, and D). (A) The opercle is wider than in other species of the genus (0.96-1.00 compared to 0.77-0.83 in †A. woodwardi, 0.91-0.92 in †A. damoni, 0.82 in †A. dolloi, and an estimated 0.80 in †A. prisca, based on our study sample). (B) There are seven to nine procurrent epaxial caudal rays (versus five or six in †A. damoni, and three in †A. dolloi; the count in †A. prisca is unknown, and the count of †A. woodwardi is within the range of †A. lepidota). (C) There are 61-65 total centra and 48-52 total vertebrae in post-juvenile stages (versus 58-61 centra and 45-48 vertebrae in †A. woodwardi, 59-60 centra and 47 vertebrae in †A. damoni, 56-57 centra and 46 vertebrae in †A. dolloi, and 70-74 centra and 55-56 vertebrae in †A. prisca). (D) There are 17-19 dorsal proximal radials (versus 14-16 in †A. woodwardi, and 15-17 in †A. dolloi; †A. damoni and †A. prisca are within the range of †A. lepidota)."

From the album: Fossils from the Plattenkalke of the Altmühl Valley
rare and beautyful: Dragonflies. But, not easy to identify... Details in the wing-structure, length of upper to lower wing... this is one we did not find the right name yet. Might be a small Cymatophlebia, but... Size is around 6 cm, Eichstaett edit: we got the name, a rare Nannogomphus, great!© fossils worldwide

Around Solnhofen at least four species of coelacanth have been recorded: Coccoderma nudum REIS 1888, Holophagus penicillata EGERTON 1861, Libys superbus ZITTEL & REIS 1888 and Macropoma willemoesii VETTER 1881 Coccoderma nudum is the smallest of these 4 species with barely more than 30cm.
