Onychophoran Orders
Onychophora (from grc, ονυχής, , "claws"; and , , "to carry"), commonly known as velvet worms (due to their velvety texture and somewhat wormlike appearance) or more ambiguously as peripatus (after the first described genus, ''Peripatus''), is a phylum of elongate, soft-bodied, many-legged panarthropods. In appearance they have variously been compared to worms with legs, caterpillars, and slugs. They prey upon other invertebrates, which they catch by ejecting an adhesive slime. Approximately 200 species of velvet worms have been described, although the true number of species is likely greater. The two extant families of velvet worms are Peripatidae and Peripatopsidae. They show a peculiar distribution, with the peripatids being predominantly equatorial and tropical, while the peripatopsids are all found south of the equator. It is the only phylum within Animalia that is wholly endemic to terrestrial environments, at least among extant members. Velvet worms are generally co ...

Cretoperipatus
''Cretoperipatus burmiticus'' is an extinct species of velvet worm that is known from Cretaceous Burmese amber approximately 100 million years old. It was found in Kachin state, Myanmar. Taxonomy The species can be assigned to one of the modern families, the Peripatidae. While only five leg pairs can be discerned, the information gained from the fossil is enough to preclude assignment to any known modern genus. Paleontology ''Cretoperipatus burmiticus'' is important in closing a gap between the only other known fossil onychophores, '' Helenodora inopinata'' from the Carboniferous and '' Succinipatopsis balticus'' plus '' Tertiapatus dominicanus'' from the Eocene and Miocene, respectively. It was hypothesised that onychophorans could have migrated from Gondwana to Southeast Asia via the northwards drift of India. Research published in 2016 concluded that the age of Burmese amber supports an earlier migration through Europe. The same study also came to the conclusion that ''T ...

Prehistoric Onychophorans
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
