Rosaceae (The rose family of plants, including apples) date back to the Eocene (56 to 33.9 million years ago) and had small-cherry-sized fruits, but apples proper didn't diverge/evolve until the late Miocene (~10 to 5 MYA).
Flowering plants totally were around in the Cretaceous ("many fossil plants recognizable as belonging to modern families (including beech, oak, maple, and magnolia) had already appeared by the late Cretaceous." -Wikipedia) but most modern botanical fruits weren't; ginkgo fruits, and not-technically-fruit "false" fruits occur on some pines, yews, and junipers, as well as berry-like fruits on gnetums and ephedra. Some of which are definitely red.
tl;dr: Apples and modern fruit didn't exist back then, so Tyra probably brought a cluster of smaller red false fruit over instead.
The hoodie I'm imagining as translation convention because Tyrannosaurs were of some degree of fluffy.
The maid outfit though? Definitely unrealistic.
