T Rex no speed de­mon

Townsville Bulletin - - NEWS -

ONE of the most ter­ri­fy­ing scenes in Steven Spiel­berg’s film Juras­sic Park showed a T Rex sprint­ing just be­hind a speed­ing Jeep.

But sci­en­tists have found that the di­nosaur would not have been able to out­run a hu­man – let alone keep up with a 4x4.

Tyran­nosaurus rex was too big to sprint that fast, they say. The sci­en­tists have worked out its max­i­mum speed for the first time and found that it was only 26km/ h. The re­searchers, from Leipzig Univer­sity in Ger­many, stud­ied al­most 500 species and found they only have so much time to reach max­i­mum speed be­cause ac­cel­er­a­tion comes from work­ing in short bursts anaer­o­bi­cally – with­out oxy­gen.
