Paradoryphoribius
Extinct genus of fossil tardigrade From Wikipedia, the free encyclopedia
Paradoryphoribius is an extinct genus of tardigrades from the order Parachela.[1][2] It is the third fossil tardigrade to be named, described in 2021 from Miocene Dominican amber from the Dominican Republic. The type, and currently only species, is P. chronocaribbeus.[3]

Discovery and naming
The holotype was discovered in Miocene Dominican amber from the Dominican Republic.[3] The amber specimen also contains three ants, a beetle, and a flower.
Paradoryphoribius chronocaribbeus was named and described by Mapalo et al. (2021),[1] making it the first extinct tardigrade known from the Cenozoic and is also the first tardigrade known from the Miocene.[4]
Description
It has a length of 539 microns.[citation needed]
Classification
In their description of Aerobius dactylus, Mapalo, Wolfe & Ortega-Hernández (2024) phylogenetically analyzed a combination of morphological features and rRNA sequences of multiple known tardigrade species. They recovered Paradoryphorybius as the sister taxon of Hexapodibius micronyx. These results are displayed in the cladogram below, with extinct species designated with a dagger (†):[5][6]
