Ancient cycads found to be pre-adapted to grow in groves

Cycads been around since before the age of the dinosaurs. Cycads living today have large, heavy seeds that suggests they rely on large fruit-eating animals to disperse their seeds. Yet there is little evidence that they are eaten and dispersed by today’s larger-bodied animals, such as elephants. If these plants are adapted for dispersal by animals that have been missing from Earth’s fauna for tens of thousands of years, how are they still around today?
