|Female Sailback Sharptooth|
The Female Sailback Sharptooth is a female Spinosaurus who makes a brief appearance alongside her mate, the Sailback Sharptooth from The Land Before Time XII: The Great Day of the Flyers, in the TV series episode The Hermit of Black Rock.
She is a dull brown color, alongside her mate. She is considerably smaller than him and has a smaller sail. This may be the sexual dimorphism of Spinosaurus in The Land Before Time.
After Swooper, Petrie, and Guido leave Black Rock, Swooper eventually gets tired and asks if it is safe for him to land and rest. Upon looking down from Swooper's back, Petrie and Guido see the Female Sailback Sharptooth and her mate standing on the ground and looking hungrily up at them. Petrie and Guido wisely tell Swooper to keep on flying.
