[dinosaur] T. rex hunting cooperation

Good day,



recently I was reading an article about what sounds did T. rex produce (

There is a hypothesis that it was producing a sinister, low-frequency
rumbling, spreading out through the ground many kilometers. 




I would like to ask, what is the possibility of T. rex using these sounds 
for communication with other tyrannosaurs in its vicinity? Is it possible 
that some individuals could chase prey animals towards others and
communicate in real time during this hunting strategy with low-frequency 
sounds? Thank you in advance! Tom
