the use of be in a descriptive clause
My reference of the following sentences is the book Summit written by Asker and Saslow.
1. The tricks that used by crows for finding food reflects the unmatchable intelligence of this species of bird.
2. Ants evolved in the era when the dinosaurs roaming on Earth.
I think in the first sentence, it must be 'that are used' and in the second one, 'dinosaurs were roaming', instead of the bolt words respectively.
Am I right?
