Polyxenida
Polyxenida is an Order (biology), order of millipedes readily distinguished by a unique body plan consisting of a soft, non-calcified body ornamented with tufts of bristles. These features have inspired the common names bristly millipedes or pincushion millipedes. This order includes about 148 species in four families worldwide, which represent the only living members of the subclass Penicillata. Description Polyxenida differ from other millipedes in having a soft, non-calcified exoskeleton, unique tufts of bristles or setae, fewer legs (no more than 17 pairs), and an absence of copulatory appendages in males. Individuals are small, usually 1.5 to 4 millimeters (0.06 to 0.16 inches) long and not exceeding 7 millimeters (0.28 inches) long. Adults in most species have 13 pairs of legs, but in one species (''Lophoturus madecassus''), they have only 11 pairs of legs, and in one genus (''Phryssonotus''), they have 17 pairs of legs, except for one species (''Phryssonotus brevicape ...

Millipedes
Millipedes (originating from the Latin , "thousand", and , "foot") are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from Latin for "thousand feet", no species was known to have 1,000 or more until the discovery in 2020 of '' Eumillipes persephone'', which can have over 1,300 legs. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures. Most millipedes are slow-moving detritivores, eating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adult synxenids possess 15 or 17 pairs of legs, with the last two pair modified for small jumps.

Phryssonotus Brevicapensis
''Phryssonotus'' is a genus of bristle millipedes containing around nine extant species.

Lebanese Amber
Lebanese amber is fossilized resin found in Lebanon and its surroundings. It dates back approximately 130-125 million years to the Barremian of the Early Cretaceous. It formed on what was then the northern coast of Gondwana, believed to be a tropical or subtropical zone in a temperate or hot climate.Raif Milki, George Poinar, Lebanese Amber: The Oldest Insect Ecosystem in Fossilized Resin, 2001. It is the oldest source of amber with a significant number of inclusions. Up to 300 sources of Lebanese amber have been recovered and 17 of them are important sources of organic inclusions, which are the oldest of their kind. The inclusions help to document Cretaceous fauna and flora. Origins Lebanese amber can be found in Lebanon and neighboring areas of the Levant. Up to 300 different sources of amber had been discovered by 2010. The amber was deposited in the Cretaceous era and is rich in fossil synclusions. 19 of the discovered sources are rich in inclusions from the Early Cretaceou ...
