Reappraisal of the Silurian placoderm Silurolepis and insights into the dermal neck joint evolution [PDF]
Silurolepis platydorsalis, a Silurian jawed vertebrate originally identified as an antiarch, is here redescribed as a maxillate placoderm close to Qilinyu and is anteroposteriorly reversed as opposed to the original description.

Ostracods of the Ordovician–Silurian boundary beds: Jūrmala core (Latvia) and its implications for Baltic stratigraphy [PDF]
Ostracods of the Ordovician and Silurian transition interval in the Jūrmala section, Latvia, were studied. The diverse pre-Hirnantian ostracod assemblage is replaced by the Harpabollia harparum association that has been recorded across the Baltoscandian

Persistent global marine euxinia in the early Silurian
The second pulse of the Late Ordovician mass extinction occurred around the Hirnantian-Rhuddanian boundary (~444 Ma) and has been correlated with expanded marine anoxia lasting into the earliest Silurian.

Three-dimensionally preserved soft tissues and calcareous hexactins in a Silurian sponge: implications for early sponge evolution [PDF]
Sponges (Porifera), as one of the earliest-branching animal phyla, are crucial for understanding early metazoan phylogeny. Recent studies of Lower Palaeozoic sponges have revealed a variety of character states and combinations unknown in extant taxa ...

Cosmopolitan myodocope ostracods from the Silurian of Uzbekistan, Central Asia
Four species of myodocope ostracod are documented from the Silurian Ludlow Series of the Aburtkan gorge on the southern slope of Dzhalpak Mountain, Uzbekistan: namely, Parabolbozoe bohemica (Barrande, 1872), Bolbozoe anomala Barrande, 1872 ...

PROSPECTS OF LITHUANIAN SILURIAN SHALE GAS, BALTIC SEDIMENTARY BASIN; pp. 357–372 [PDF]
The Baltic sedimentary basin contains numerous hydrocarbon fields in Lithuania. The Lower Silurian shales are considered as potential for shale gas exploration. The thickness of shale units within the oil window ranges from 115 to 180 m in west Lithuania.
