Archipelepis is a genus of extinct thelodont agnathans, and are the most primitive recognized thelodonts of which whole body fossils are known.

[2] Fossils of bodies and scales are currently known from Late Telychian to Wenlock-aged marine strata of northern Canada.

[3] Both species have similar body morphology, in that both resembled tadpoles with forked tails.

Scale morphology differs in that A. bifurcata has forked scales with two prong-like spires,[1] and that A. turbinata has bulbous, pointed scales that resemble upside-down spinning tops.
