The confirmed digging input is hold-and-release: use your shovel on a dig site, hold while the meter moves and release in the green area. PC, mobile and console are supported; exact riding and diving bindings remain unconfirmed.

Time the release
Use the green segment as your release cue. The instruction is to let go while the meter is green, rather than simply holding for the longest possible time.
What this control applies to
This instruction is specifically for fossil dig sites. It does not establish the fishing, spear, diving or riding input, so do not carry the digging meter rule over to those activities.
Keyboard, touch and controller
Use the dig-site interaction shown by your device. The public description supplies an action but no named keyboard key or controller button. A complete cross-platform key table needs current interface evidence.
