This enormous creature took on a T-Rex and won in ‘Jurassic Park 3’, but what’s it called?

Interesting fact:

Until the year 1923, scientists were unsure how dinosaur babies were born! Then explorer Roy Chapman Andrews uncovered the first dinosaur nest known to science, located in the Gobi Desert of Mongolia. We now know that the largest dinosaur eggs could be bigger than basketballs, with seriously thick shells. In fact, the bigger the shell the thicker the egg! This means that some of the poor babies probably wouldn’t have been able to get out of their eggs were they any larger.
