This is Calathea rufibarba.
Its pot size is way too big, and the soil mix looks very heavy. It also most likely did not get enough humidity.
It may not be done, I'd unpot it and see if you do indeed have any viable roots left. If you do repot it into a very tiny pot, like 2", in a better draining soil mix. If you can get it to re-sprout and put out new growth, only size up the pot extremely slowly, and give this plant as much humidity as you can
