Hypnum spec., Orthostichella cf. pentasticha, Syrrhopodon flexifolius and Porotrichum aff. substriatum are recorded from Dominican amber (c. 25 mio yrs. b.p.). The first two species were known before from Dominican amber, the last two are newly reported. Dominican amber is a rich source for fossil mosses from the Tertiary (Eocene to Pliocene), by the same time a chance for reconstruction of the...

The Eocene elmid beetles known from Baltic amber so far are reviewed, and their natural environment is discussed. Palaeoriohelmis samlandica Bollow, 1940 is re-described based on examination of the holotype. The genus Palaeoriohelmis Bollow, 1940 is synonymized with Heterlimnius Hinton, 1935, and Palaeoriohelmis samlandica is transferred to Heterlimnius (H. samlandicus comb. nov.). Heterelmis g...

Based on a single well-preserved specimen from Eocene Baltic amber, Lilioceris groehnisp. n. is described and illustrated using phase-contrast X-ray microtomography. It is the first described species of Criocerinae (Coleoptera: Chrysomelidae) from Baltic amber. A check-list of fossil Criocerinae is provided. Placement of Crioceris pristiana (Germar, 1813) is discussed, this species is removed f...

In drug discovery, protonation states and tautomerization are easily overlooked. Through a Merck-Rutgers collaboration, this paper re-examined the initial settings and preparations for the Thermodynamic Integration (TI) calculation in AMBER Free-Energy Workflows, demonstrating the value of careful consideration of ligand protonation and tautomer state. Finally, promising results comparing AMBER...

The Amber El Amino area is located 75 kilometres southeast of Prince Rupert. Access to the area is by helicopter from Prince Rupert or Terrace (Figure 1). The El Amino showing (BC MINFILE 103H 071) is located on Sulphide Creek (Figure 2) which drains eastward into Hanna (El Amino) Creek. The Amber showing (BC MINFILE 103H 171) is located 700 metres north of the El Amino showing. Hanna Creek dra...

Abstract Cockroaches (Blattaria s. str.) were documented from numerous amber localities around the world, representing both extinct and extant families. Alienopteridae is an cockroach family known only Cretaceous of Gondwana (Brazil, Botswana, Myanmar amber) Cenozoic North America. Alienopterix santonicus sp. n. Late Ajka Coal Formation (Bakony Mts, western Hungary) extends rich geographical di...
