Fleetwood Town were outbattled as their automatic promotion push stalled on derby day at Highbury.
All looked rosy when Antoni Sarcevic stroked home a free kick after nine minutes to give the home side the lead.
But a soft header from a soft corner let Morecambe back in, Mark Hughes heading home at the back post as Chris Maxwell hesitated.
Ian Hume had a shot cleared off the line before the break but Fleetwood failed to take control.
And they were made to pay 18 minutes from time when James Devitt’s cross was flicked past his own keeper by Nathan Pond.
Town piled on the pressure and did grab an equaliser, Jon Parkin’s shot saved by Barry Roche, the ball falling for Hume to tap home.
Robbie Threlfall almost grabbed the spoils for the visitors, Charlie Taylor’s dramatic diving header denying the Morecambe sub when Maxwell looked beaten.
