  We experimentally generate cylindrically polarized wavepackets with
transverse orbital angular momentum, demonstrating the coexistence of
spatiotemporal optical vortex with spatial polarization singularity. The
results in this paper extend the study of spatiotemporal wavepackets to a
broader scope, paving the way for its applications in various areas such as
light-matter interaction, optical tweezers, spatiotemporal spin-orbit angular
momentum coupling, etc.
