Narrative:

We were held short of runway 35C on taxiway Z behind 2 aircraft when tower issued numerous clrncs to cross. We followed aircraft across runway. Radios were busy with clrncs and readbacks. We were unsure of whether we were part of the clrncs and realized we were already on the runway. We continued to cross and held short of runway 35L. It was day VFR and runway was clear. Tower did not mention any problems with our taxi and we were cleared across runway 35L and handed off to ground for further taxi. We did not receive any indications from controllers that an incursion took place. Supplemental information from acn 504979: tower said nothing to us, but it is possible that we crossed without clearance.
