Eucnemidae
Eucnemidae, or false click beetles, are a family of elateroid beetles including about 1700 species distributed worldwide. Description Closely related to the family Elateridae, specimens of Eucnemidae can reach a length of . Bodies are slightly flattened and convex. The upper surfaces of the body usually has hairs, setae or scales. Ecology The larvae are typically legless, and generally develop feeding on the fluids of rotting wood, likely vomiting digestive enzymes into the wood to break apart the fungal hyphae, moving using their shovel shaped heads to force apart the wood. Adults, which are typically found on broken surfaces of trunks and stumps, have a short lifespan and it is unclear whether they feed, though they are capable fliers, and like some other elateroids are capable of clicking.

Elateroidea
The Elateroidea are a large superfamily of beetles. It contains the familiar click beetles, fireflies, and soldier beetles and their relatives. It consists of about 25,000 species. Description Elateroidea is a morphologically diverse group, including hard-bodied beetles with 5 abdominal ventrites, soft-bodied beetles with 7-8 ventrites connected with membranes (formerly known as cantharoids), and beetles with intermediate forms. They have a range of sizes and colours, but in terms of shape, they are usually narrow and parallel-sided as adults. Many of the sclerotised elateroids (Cerophytidae, Eucnemidae, Throscidae, Elateridae) have a clicking mechanism. This is a peg on the prothorax which fits into a cavity in the mesothorax. When a click beetle bends its body, the peg snaps into the cavity, causing the beetle's body to straighten so suddenly that it jumps into the air. Most beetles capable of bioluminescence are in the Elateroidea, in the families Lampyridae (~2000 specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Talbragar Fossil Site
The Talbragar fossil site is a paleontological site of Late Jurassic (Tithonian) age in the central west of New South Wales, Australia. It lies about north-east of the town of Gulgong, and north-west of Sydney. The site has been known for over a century during which it has been extensively excavated to the point of near exhaustion. It is now registered as a Crown Land Reserve for the preservation of fossils; access is by permit, and the collection of rocks and fossil specimens is prohibited. The reserve is listed on the (now defunct) Register of the National Estate. Fossils The fossil-bearing rocks are fine-grained siltstones and mudstones that are part of the Purlawaugh Formation. They occur mainly as loose blocks and weathered shales over an area of about , with a thickness of no more than . They are thought to be the remnants of sediments from a small freshwater lake, surrounded by forest, which existed about 175 million years ago when Australia was part of Gondwana. ...

Elateridae
Elateridae or click beetles (or "typical click beetles" to distinguish them from the related families Cerophytidae and Eucnemidae, which are also capable of clicking) are a family of beetles. Other names include elaters, snapping beetles, spring beetles or skipjacks. This family was defined by William Elford Leach (1790–1836) in 1815. They are a cosmopolitan beetle family characterized by the unusual click mechanism they possess. There are a few other families of Elateroidea in which a few members have the same mechanism, but most elaterid subfamilies can click. A spine on the prosternum can be snapped into a corresponding notch on the mesosternum, producing a violent "click" that can bounce the beetle into the air. Clicking is mainly used to avoid predation, although it is also useful when the beetle is on its back and needs to right itself. There are about 9300 known species worldwide, and 965 valid species in North America. Etymology Leach took the family name from the g ...

Burmese Amber
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to its alleged role in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected. Geological context, depositional environment and age The amber is found within the Hukawng Basin, a large Cretaceous-Cenozoic sedimentary basin within northern Myanmar. The s ...

Beetles Described In 1829
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exoske ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Dominican Amber
Dominican amber is amber from the Dominican Republic derived from resin of the extinct tree ''Hymenaea protera''. Dominican amber differentiates itself from Baltic amber by being nearly always transparent, and it has a higher number of fossil inclusions. This has enabled the detailed reconstruction of the ecosystem of a long-vanished tropical forest.George Poinar, Jr. and Roberta Poinar, 1999. ''The Amber Forest: A Reconstruction of a Vanished World'', (Princeton University Press) Age A study in the early 1990s returned a date up to 40 million years old. However, according to Poinar, Dominican amber dates from Oligocene to Miocene, thus about 25 million years old. The oldest, and hardest of this amber comes from the mountain region north of Santiago. The ''La Cumbre'', ''La Toca'', ''Palo Quemado'', ''La Bucara'', and ''Los Cacaos'' mining sites in the ''Cordillera Septentrional'' not far from Santiago. Amber has also been found in the south-eastern Bayaguana/Sabana de la Mar a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
