PART BROKE UNDER THE CAR, NEXT TO THE LEFT REAR TIRE, WHAT IS IT

1998 Nissan Altima • 170,000 miles

Part broke under the car, next to the left rear tire, opposite to the exhaust. It looks like a black box and it is filled with some carbon-looking stuff. Dont know how else to describe it.
What is it and how critical is it? I need to travel.

Could be the catalytic converter. A picture will help as there are several dozen parts under the car.
