  We experimentally generate two-dimensional Jones-Roberts solitons in a
three-dimensional atomic Bose-Einstein condensate by imprinting a triangular
phase pattern. By monitoring their dynamics we observe that this kind of
solitary waves are resistant to both dynamic (snaking) and thermodynamic
instabilities, that usually are known to strongly limit the lifetime of dark
plane solitons in dimensions higher than one. We additionally find signatures
of a possible dipole-like interaction between them. Our results confirm that
Jones-Roberts solitons are stable solutions of the non-linear Schr\"odinger
equation in higher dimensions and promote these excitations for applications
beyond matter wave physics, like energy and information transport in noisy and
inhomogeneous environments.
