What type of aircraft is an ER4?

[coco50]

OK I know that an Swm is a metroliner, a DH8 is a Dash 8 and a 743 is a B747 - 300 series, but what is an ER4? I see that I have to fly on one operated bt American Eagle from DFW to CHS. The seat map shows that it has an A seat for 18 rows, an aisle and B and C seats for 18 rows. Can someone enlighten me?:?:

Great plane for viewing the countryside, ask for an A side if by one self.
Flew it recently from Reagan to JFK, and flew along the coast. Great view in over NY too.

just flew into ORD in an ER4 from MQT. nice plane, quiet if you are sitting towards the front. they seem to me to have larger than normal windows and you get a great view.
