Lady Margaret, a large Triceratops alpha, was native to Isla Nublar. She attacked the gate that Gerry and Jess Harding were trying to close because she was attracted to the honking of the jeep‘s horn. Margret then proceeded to charge the jeep repeatedly until Jess shut off the horn. Lady Margret met her apparent end when she engaged in mortal combat with Isla Nublar’s Tyrannosaurus.
