Miniature Snail in a Rock Sandwich

First fossil record of thorn snails in the southern United States

Researchers from the USA and Switzerland, including Senckenberg scientist and first author Dr. Adrienne Jochum, have described the first fossil Carychium land snails from Florida. The rock layer containing the snail fossils, which are only a few millimeters in size, was accidentally uncovered during construction work and dates from the Pleistocene period between 2.58 million and 11,700 years ago. In their study, published in the open-access journal ZooKeys, the scientists also describe a previously unknown carychiid fossil species.

The tiny snails of the genus Carychium with a maximum height of 2.5 millimeters and a width of 1.5 millimeters are known mostly east of the Mississippi River in the USA and from eastern Canada, Mexico and Jamaica as well as in sheltered humid habitats in Central America to Panama. “However, unlike the extant species, fossilized thorn snails are rarely found east of the Mississippi River. In our recent field work we have now provided the first fossil record of the genus in the southeastern United States, as well as the first fossil record ever for the species Carychium floridanum,” explains Dr. Adrienne Jochum of the Senckenberg Research Institute and Natural History Museum in Frankfurt and the Natural History Museum in Bern.

During the construction of a track bed for the Brightline railroad, which will connect Port Canaveral with Orlando International Airport, civil engineers accidentally came across a one-meter-thick layer of fossilized non-marine gastropods between two marine shell beds. “This ‘rock sandwich’ was formed during the Pleistocene, a geologic era characterized by repeated glaciations, climate changes, and fluctuations in water level that greatly influenced and shaped the region around present-day Florida. The shell layer is sandwiched between rock layers from the Lower Pleistocene, 2.58 to 0.77 million years ago, and the Upper Pleistocene, 140,000 to 120,000 years ago, and contains 14 freshwater and 28 terrestrial snail species.”

Among them is the snail Carychium floridanum, whose current representatives still live in humid, forested, and undisturbed habitats in central and northern Florida. The researchers also described a new species, Carychium nashuaense, which is less than 1.6 millimeters long and was previously unknown to science.

“To dislodge the fossil miniature snails from the rock layers, we first washed them through a graduated series of sieves. Next, 32 Carychium shells were culled under a microscope from a mixture of other mollusks and rock debris. A high-resolution X-ray tomograph helped us examine the spindle structure inside the fragile fossil shells and compare them with 3D reconstructions of the inner shell of still-living thorn snail species from the southeastern U.S., Mexico, Central America, and Jamaica,” explains Jochum.

While the design of the inner shell structure of Carychium floridanum has changed little from the Pleistocene to the present, the shell structure of Carychium nashuaense suggests a relationship with Central American Carychium relatives. “We suspect that the spread of the snails occurred via birds, mammals, and reptiles, who transported the small snails in their guts, fur, or feathers to the wetlands from which the alluvial sediments in the rock layer we studied originated. The subsequent mixing with other members of the genus led to the emergence of new species,” adds Jochum in conclusion.

Fossil Record, a Natural History Museum of Berlin journal moves to ARPHA

Having been publishing its historically renowned Deutsche Entomologische Zeitschrift and Zoosystematics and Evolution in partnership with Pensoft since 2014, the Museum extends the collaboration by moving a third signature journal

Having been publishing its historically renowned scientific journals Deutsche Entomologische Zeitschrift (DEZ) and Zoosystematics and Evolution (ZSE) in partnership with the scholarly publisher Pensoft and its ARPHA Platform since 2014, the Natural History Museum of Berlin (Museum für Naturkunde Berlin) now extends the collaboration by moving a third signature journal: Fossil Record

Launched in 1998 under the name Mitteilungen aus dem Museum für Naturkunde Berlin, Geowissenschaftliche Reihe, Fossil Record is the Natural History Museum of Berlin’s palaeontological journal. Published in two issues a year, the open-access scientific outlet covers research from all areas of palaeontology, including the taxonomy and systematics of fossil organisms, biostratigraphy, palaeoecology, and evolution. It deals with all taxonomic groups, including invertebrates, microfossils, plants, and vertebrates.

Following its move to ARPHA, Fossil Record is to utilise the whole package of ARPHA Platform’s services, including its fast-track, end-to-end publishing module, designed to appeal to readers, authors, reviewers and editors alike. 

With ARPHA, each submitted manuscript is carried through the review, editing, publication, dissemination and archiving stages without leaving the platform’s collaboration-centred online environment. The articles are made available in PDF and machine-readable JATS XML formats, as well as semantically enriched HTML for better and mobile-friendly reader experience. 

As a result, the journal’s articles are as easy to discover, access, reuse and cite as possible. Once published, the content is indexed and archived instantaneously and its underlying data exported to relevant specialised databases. Simultaneously, a suite of various metrics is enabled to facilitate tracking the usage of articles and sub-article elements, such as figures and tables.

“We have deeply enjoyed our collaboration with the Natural History Museum of Berlin for the past seven years that started with two great journals moving to our scholarly portfolio and advanced open access. Now, I am delighted to strengthen this wonderful partnership by welcoming Fossil Record and its fantastic editorial team to the families of ARPHA and Pensoft. I am certain that together we will not only repeat the success we had with DEZ and ZSE, but will actually build on it,”

says Prof. Dr Lyubomir Penev, founder and CEO at ARPHA and Pensoft.

Pensoft welcomes SNSB’s paleontology and geobiology journal Zitteliana to its portfolio

The first papers of the journal of the Bavarian State Collection of Palaeontology and Geology in Munich since the move to Pensoft’s publishing platform are now online

The scholarly publisher and technology provider Pensoft welcomes the latest addition to its diverse portfolio of scientific outlets – the open-access, peer-reviewed journal Zitteliana, which publishes research in the fields of paleontology and geobiology.

Zitteliana is a journal of the Bavarian State Collection of Palaeontology and Geology Munich, which is part of the State Natural History Collection of Bavaria (SNSB), a research institution for natural history comprising five state collections.

Published both online and in print, the journal contains original articles, short contributions and reviews on all aspects of palaeontology and geobiology, welcoming research on all regions of the Earth and all periods of geologic time. The journal invites both modern and traditional research outputs, including palaeobiology, geobiology, palaeogenomics, biodiversity, stratigraphy, sedimentology, regional geology, systematics, phylogeny, and cross-disciplinary studies of these areas.

Since its launch in 1961, the journal has changed its name several times (i.e. Mitteilungen der Bayerischen Staatssammlung für Paläontologie und historische Geologie, Zitteliana A (Abhandlungen) and Zitteliana B (Mitteilungen)), and has extended both scope and thematic range to  cover global research from all areas of palaeontology and geobiology.

“This year, Zittelliana is celebrating its 60th anniversary in brand new gear. The move to the innovative scholarly publisher Pensoft shows how tradition can work hand in hand with innovation and modernity. We are very excited about this relaunch and very much look forward to transforming  Zitteliana into an internationally leading journal in Paleontology and Geobiology together with Pensoft,” the journal’s Editor-in-Chief, Professor Gert Wörheide adds.

After moving to Pensoft’s scholarly publishing platform ARPHA, and with a brand-new, user-friendly website, Zitteliana now takes full advantage of ARPHA’s signature fast-track, end-to-end publishing system, which significantly improves user experience for authors, reviewers and editors alike. The collaboration-focused platform supports manuscripts in all steps of the publishing process – submission, peer review, editing, publication, dissemination and archiving, all within its online environment. To the benefit of readers, published articles are then made available in PDF, machine-readable JATS XML formats, and semantically enriched HTML, which makes them much easier to discover, access, cite and reuse.

In addition, ARPHA Platform offers a long list of high-tech features and human-provided services such as advanced data publishing, linked data tables, semantic markup and enhancements, automated export of sub-article elements and data to aggregators, sub-article-level usage metrics, and web-service integrations with more than 40 world-class indexing and archiving databases.

The journal’s first papers published with Pensoft are already publicly available. One of the studies, authored by Norbert Wannenmacher, Volker Dietze, Matthias Franz of the state office for geology, resources and mining at Freiburg’s regional council, and Günter Schweigert of the Stuttgart State Museum of Natural History, describes three new fossil species from south-western Germany.

Zitteliana is the latest in a series of biodiversity-themed journals to join the Pensoft family – earlier this year the ichthyology journal Acta Ichthyologica et Piscatoria signed with the scholarly publisher and moved on to ARPHA Platform.
