An artificial disc implant and associate methods and instrumentation are provided for the artificial disc implant that includes opposite vertebral endplate members and a spacer member between the vertebral endplate members. An anchoring member extends from at least one of the vertebral endplate members toward an adjacent vertebral endplate when the implant is positioned between vertebrae. The anchoring member can be received in an anchor seat formed in the adjacent vertebral endplate without requiring the artificial disc implant to be impacted into the space between vertebrae to engage the anchoring member in the seat.
