False Ground Beetle
The Trachypachidae (sometimes known as false ground beetles) are a family of beetles that generally resemble small ground beetles, but that are distinguished by the large coxae of their rearmost legs. There are only six known extant species in the family, with four species of ''Trachypachus'' found in northern Eurasia and northern North America, and two species of ''Systolosoma'' in Chile and Argentina. They were much more diverse in the past, with dozens of described species from the Mesozoic. Their habits are similar to those of the ground beetles; they are usually found in the leaf litter of conifer forests, and are thought to be mostly predators and scavengers, active during the day ( diurnal). According to entomologist George Ball, "the most interesting thing about this small family is its uncertain phylogenetic relationships"; it has previously been classified as a subfamily of Carabidae, and as a family been placed in several different positions relative to other beetle ...

Fossil Beetle Genera
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the a ...
