Thanahita is a genus of extinct lobopodian and known from the middle Silurian Herefordshire Lagerstätte at the England–Wales border in UK.

[2][3][4] Thanahita was discovered in 2018 during a palaeontological expedition funded by the Natural Environment Research Council (NERC) and the Leverhulme Trust.

[5][6][2] The only fossil of Thanahita (designated OUMNH C.29699) was collected from the upper part of Wenlock Series of the Lagerstätte.

These papillae are not uniformly present in each transverse line of the body, and are in pairs in some part but singly in the posterior region.

[1] Thanahita possess some shared features (e.g. anterior pairs of slender legs; reduced tail[2]) with Cardiodictyon, Carbotubulus, and Hallucigenia, which have been classified within a single lobopodian family Hallucigeniidae.
