Matt Richards' injury-time goal ensured Shrewsbury fought back from 2-0 down to maintain their unbeaten home record with a draw against in-form Oxford.
Lee Holmes put the U's ahead inside the first minute with a shot from just outside the area before lifting the ball over Chris Neal for his second.
Mark Wright pulled a goal back after the break, firing in Marvin Morgan's cross from inside the area.
And Richards completed the comeback with a dramatic 35-yard strike.
Shrewsbury are now unbeaten at the Greenhous Meadow in their last 25 games.
VIEWS FROM THE DRESSING ROOM
Shrewsbury manager Graham Turner told BBC Radio Shropshire:
"It was a disappointing first 45 minutes, we never got started - but it was a terrific second half performance finished off with two very good goals.
"It was a good finish from Mark Wright - he's got a knack for that and with 10 goals this season that's a first class record for a wide player. And Matt Richards' strike right at the death, it flew in, it was a terrific finish.
"It was a good comeback against a side who are no mugs, so we shouldn't detract from the manner in which we played second half and the fightback to secure a point."
Oxford United manager Chris Wilder told BBC Radio Oxford:
"We pushed them hard and there were a lot of tired legs out there.
"We are disappointed but we will move on and the boys can take a lot of credit from their performance and I think they were absolutely magnificent.
"We've hit the bar to make it 3-0 and I don't think they could cope with us in the first half but we've given the ball away too easily in the second 45 minutes.
"We've been undone by a super strike. It was a fantastic strike. I think there are a lot of things that went against us. We didn't get anything off the referee and I had a bad feeling before the game about him if I'm honest.
"He was on first name terms with them and it was the first time he's refereed us - we didn't get a decision all night. It's a tough enough place to come but maybe this is a pivotal week for us in terms of the belief we can take from the two results."
