Eopagetia, Mesopagetia Pagetia is a genus of small trilobite, assigned to the Eodiscinid family Pagetiidae and which had global distribution during the Middle Cambrian.

Pagetia bootes Walcott, 1916, from the middle Cambrian (late Wuliuan or base Drumian) Burgess Shale fossil Lagerstätte.

The species occurs with Ptychagnostus praecurrens and derives originally from the "greater phyllopod bed" of Walcott quarry on "Fossil Ridge" between Wapta Mountain and Mount Field, approximately 5 kilometres north of Field, British Columbia in the Canadian Rocky Mountains.

In the type species, Pagetia bootes Walcott, 1916, there is a well-defined preglabellar median furrow separating the genae.

Pygidial axis is well defined, reaching or overhanging the posterior border, usually with five rings and commonly extending backwards into a prominent postaxial spine.
