A new proposal concerning the botanical origin of Baltic amber.
Baltic amber constitutes the largest known deposit of fossil plant resin and the richest repository of fossil insects of any age. Despite a remarkable legacy of archaeological, geochemical and palaeobiological investigation, the botanical origin of this exceptional resource remains controversial. Here, we use taxonomically explicit applications of solid-state Fourier-transform infrared (FTIR) m...
متن کاملInsect frass in Baltic amber
Inclusions of wood debris loosened from pine-like trees are abundant in Baltic amber of Eocene and Oligocene age. The possibilities to find insect frass and excrement among wood debris are outlined and some examples are given. Comparison with the frass and excrement produced by present-day insects provide a possibility to identify insects even though their fossils are lacking. This information ...
متن کاملHydrochemistry and stable isotopes study of the precipitation at Haraz Basin, north of Iran
Stable isotopes (Deuterium and Oxygen-18) have a broad application in many of water related sciences. Precipitation is the most important input to the water cycle which shows considrable spatial and temporal variability in its isotope content. To study the precipitation isotope content, 51 samples from August 2015 to July 2016 have been collected mainly on a monthly basis with few events based ...
متن کاملFirst record of the family Ithonidae (Neuroptera) from Baltic amber.
Elektrithone expectata gen. et sp. nov. (Neuroptera: Ithonidae) is described from Eocene Baltic amber and represents the first record of this family from Baltic amber. The forewing venation of the new genus is characterized by a small number of crossveins as found in some 'polystoechotid'-like genera, and by the absence of the distal nygma and the strong reduction of the anal area which are cha...
متن کاملEvaporative fractionation of volatile stable isotopes and their bearing on the origin of the Moon.
The Moon is depleted in volatile elements relative to the Earth and Mars. Low abundances of volatile elements, fractionated stable isotope ratios of S, Cl, K and Zn, high μ ((238)U/(204)Pb) and long-term Rb/Sr depletion are distinguishing features of the Moon, relative to the Earth. These geochemical characteristics indicate both inheritance of volatile-depleted materials that formed the Moon a...
