Introduction

A paleontologist at work at John Day Fossil beds National Monument

Paleontology (/ˌpliɒnˈtɒləi, ˌpæli-, -ən-/ PAY-lee-on-TOL-ə-jee, PAL-ee-, -⁠ən-), also spelled palaeontologyorpalæontology, is the scientific study of life that existed prior to the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuvier's work on comparative anatomy, and developed rapidly in the 19th century. The term has been used since 1822 formed from Greek παλαιός ('palaios', "old, ancient"), ὄν ('on', (gen. 'ontos'), "being, creature"), and λόγος ('logos', "speech, thought, study").

Paleontology lies on the border between biology and geology, but it differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry, mathematics, and engineering. Use of all these techniques has enabled paleontologists to discover much of the evolutionary history of life, almost back to when Earth became capable of supporting life, nearly 4 billion years ago. As knowledge has increased, paleontology has developed specialised sub-divisions, some of which focus on different types of fossil organisms while others study ecology and environmental history, such as ancient climates.

Protomycena closeley resembled this modern Mycena.
Protomycena closeley resembled this modern Mycena.

Protomycena is an extinct monotypic genusofgilled fungus in the Mycenaceae family, of order Agaricales. At present it contains the single species Protomycena electra, known from a single specimen collected in an amber mine in the Cordillera Septentrional area of the Dominican Republic. The fruit body of the fungus has a convex cap that is 5 mm (0.2 in) in diameter, with distantly spaced gills on the underside. The curved stipe is smooth and cylindrical, measuring 0.75 mm (0.030 in) thick by 10 mm (0.39 in) long, and lacks a ring. It resembles extant (currently living) species of the genus Mycena. Protomycena is one of only five known agaric fungus species known in the fossil record and the second to be described from Dominican amber. (see more...)

    The Palanga Amber Museum.
    The Palanga Amber Museum.

    The Palanga Amber Museum, near the Baltic SeainPalanga, Lithuania, is a branch of the Lithuanian Art Museum. It is housed in the restored 19th-century Tiškevičiai Palace and is surrounded by the Palanga Botanical Garden. The museum's collection of amber comprises about 28,000 pieces, of which about 15,000 contain inclusions of insects, spiders, or plants. About 4,500 pieces of amber are exhibited; many of these are items of artwork and jewelry.

    The first floor is dedicated to displays that illustrate the formation and composition of amber. Amber in the area arose from deltaic deposits of rivers flowing from Fennoscandia in the Eocene Period, about 40 to 45 million years ago. The processes via which resin is changed into amber by microorganisms, oxidation, and polymerization are illustrated. Samples of microdrops and microicicles (i.e. "amber within amber") are among the displayed items. The museum holds Europe's third largest amber specimen, the "Sun Stone", of size 210x190x150 mm and weighing 3,526 grams, which has been stolen twice. Amber from other areas of the world is also part of the collection.(see more...)

    Stone-age human remains in the Tomb of Téviec

    Two skeletons of women between 25 and 35 years of age preserved in the Tomb of Téviec. The tomb is dated to the Mesolithic between 6,740 and 5,680 years ago. They died a violent death, with several head injuries and impacts of arrows. The two bodies were buried with great care in a pit half in the basement rock (underlying or country rock) and half in the kitchen debris that covered them. The tomb is protected by antlers. The grave goods include flint and bone (mainly wild boar) offerings and funeral jewelry which is made of marine shells drilled and assembled into necklaces, bracelets and ankle ring. Some of the bone objects have engraved lines. The tomb was recovered in 1938 and restored in 2010.
