Claim 0:
1. A floor panel, comprising:
a core provided with an upper surface, a lower surface, a first core flank at a first side of the core, and a second core flank at a second side of the core, wherein the first core flank comprises a first core flank upper portion that connects to the upper surface;
a first coupling part and a second coupling part provided at the first side and the second side of the core, respectively;
wherein the first coupling part comprises:
a first tongue having a first inner side flank, a first outer side flank, and a first upper portion flank connecting the first inner side flank to the first outer side flank;
a first bridging part connecting the first tongue to the core;

wherein the second coupling part comprises:
a second tongue having a second inner side flank, a second outer side flank, and a second upper portion flank connecting the second inner side flank to the second outer side flank, wherein the second outer side flank comprises a second outer side flank upper portion that connects to the upper surface;
a second bridging part connecting the second tongue to the core;

wherein the first inner side flank, the first bridging part, and the first core flank define a first groove and wherein the second inner side flank, the second bridging part, and the second core flank define a second groove;
wherein the floor panel is configured to be coupled to an adjacently arranged further floor panel that is identical to said floor panel in such a manner that the first tongue of the floor panel is received in the second groove of the adjacently arranged further floor panel and that the second tongue of the adjacently arranged further floor panel is received in the first groove of the floor panel thereby providing a first locking in a first direction substantially parallel to the upper surface;
wherein at least a part of the first core flank upper portion of the first core flank and at least a part of the second outer side flank upper portion of the second outer side flank are inclined such that when the floor panel is coupled to the adjacently arranged further floor panel these upper portions lie against each other for the purpose of providing a second locking in a second direction substantially perpendicular to the upper surface;
in that the first upper portion flank of the first tongue comprises a curved recess that connects to the first inner side flank at a first angle (α) in between 90° and 150°, wherein the first inner side flank extends from the curved recess towards the first bridging part and towards the core, and wherein the second groove comprises a bulge that is shaped substantially complementarily to the curved recess and is configured such that it is received in the curved recess when the floor panel is coupled to the adjacently arranged further floor panel, and
wherein the first inner side flank extends from the curved recess towards the first bridging part and towards the core at a second angle relative to a normal of the lower surface that is in between 0° and 45°.
