A new chance on coinage of hirsute land snail has been rule utterly preserved in a piece of 99 - million - year - old Mesozoic gold . The blurred mollusk has been namedArchaeocyclotus brevivillosus , deriving from the Latin " brevis " meaning small , and " villōsus " meaning hairy .
The specimen was first collected before 2017 from an amber mine in the Hukawng Valley in Burma . Observed using a combination of classical microscopy and 3D X - ray micro - computed tomography , the snail measures 26.5 mm ( 1 inch ) in duration and 21 millimeters ( 0.8 inches ) widely , and is 9 millimeters ( 0.4 inches ) tall with ok hairs just 150 - 200 micrometers in length running along its carapace .
Of the eight metal money of theCyclophoridaefamily that were pile up from Burmese gold , six were found to have these fuzzed shells . imprint from the uppermost proteinaceous layer of the case , these fine hairs are not uncommon on the shells of both living and extinct land snails from several unlike families . The convergent phylogenesis of these clear-cut families suggest there is a pregnant evolutionary vantage to having a hirsute shell .

“ [ They ] could improve the animals ’ ability to better cling to plant stalks or leaves – something that has already been keep an eye on in present - Clarence Shepard Day Jr. snails , ” explained Dr Adrienne Jochum from the Senckenberg Research Institute and Natural History Museum in Frankfurt , and the Natural History Museum in Bern , in astatement .
Additionally , Jochum explained , the hairs are thought to play a part in thermic regulation by enabling piss droplets to adhere to the shell . They may have also aided in the bar of erosion by acidic soil and leaf bedding while serving as a contour of disguise and perhaps even playing a office in teammate pick .
The presence of such whisker on the majority of the cyclophorid species found in the Cretaceous Burmese gold suggests that this is the transmissible state of the farming escargot . The hairs may even have played a role in the group ’s terrestrialization during the Mesozoic period , find out the snail transition from water to bring down between 252 and 66 million eld ago .
Myanmar amber play a huge theatrical role in the preservation of ancient species in an surroundings otherwise perfectly suitable to the disintegration of constitutive cloth . Over2,000unique species from the Cretaceous flow have been found preserved in Myanmar amber , including an unusualviviparous snailencased with its freshly contain unseasoned .
These elaborate saving enable investigator to fill in gaps in the fossil record and study unequaled physical features of long - extinct specimen .
