BVP Fieldtrip to Solnhofen Limestone (Jurassic of Germany) + Museum visit
ziggycardon posted a topic in Fossil Hunting Trips
Hi Everyone! A couple of days ago I returned from a fieldtrip to the Solnhofen region in Germany. The trip was organized by my fossilclub the BVP as well as my friend and professional paleontologist Jonathan Wallaard who led the trip. During our 4 day stay we visited 3 different quarries and the Burgermeister-Müller-Museum in Solnhofen. The Solnhofen Limestone is probably one of the most famous Konservat-Lagerstätte in the World. Dating back to the late Jurassic, Tithonian around 152 - 150 million years ago. During this time this area was a tropical archipelag- 29 replies

The genus previously known as Ophiopsis Agassiz, 1834 (except Ophiopsis muensteri Agassiz, 1834), was reassigned by Lane & Ebert 2015 to Ophiopsiella. Taxonomy from Lane & Ebert 2015. Lane & Ebert 2015, p. e883238-4 :”Diagnosis—The genus Ophiopsiella is characterized by the following unique combination of features: medium-sized halecomorph fishes with body depth increased anteriorly to form a low hump and tapering posteriorly; parietals equal in length to dermopterotics; antorbitals do not reach the orbit; lacrimal large and deep; *low number of suborbitals with ventral-most

Taxonomy from Fossilworks.org. The state of preservation of Magila is mostly poor, which becomes understandable when you consider that Magila was a burrowing crustacean living in the ground. Therefore, a more calcified carapace was not necessary. Only the exceptionally wide claws are mostly well preserved. These probably also served for digging. Diagnosis from Garassino & Schweigert 2006, p. 22: “Carapace cylindrical laterally flattened; deep cervical groove strongly directed forward; one or two carinae weak in antennal region; rostrum short and edentate; antennal spine well developed;

Taxonomy from Fossilworks. From Ebert 2014, p. 39: "Belonostomus sphyraenoides Agassiz, 1844 is known only from the Eichstätt basin. Belonostomus is very rare in the Plattenkalk basin of Eichstätt and as far as I know, all specimens belong to B. sphyraenoides. The Plattenkalk of Eichstätt is dated as eigeltingense β horizon of the Tithonian (Schweigert et al. 2013). Belonostomus sphyraenoides has about 71 vertebrae and 71 lateral line scales."

Three species of Thylacocephala have been described from the Solnhofen Formation (“Solnhofen lithographic limestones”) so far: Clausocaris lithographica, Dollocaris michelorum, and Mayrocaris bucculata. A fourth new genus and species was newly described in 2019: Falcatacaris bastelbergeri.
