The mildly deranged penguin says that’s the remains of a T. rex nest after being overrun by dodos. Most likely, she says, the dodos were ecstatically dancing, a sight which once seen can unfortunately never be forgotten. She says you can tell its an overrun T. rex nest by the absence of any T. rex.
Those are galls, but more detail I do not know.
