Hister unicolor (Linnaeus, 1758)
The Histeridae are a notoriously difficult group of beetles to ID and ideally, a specimen is needed to key out to ensure correct identification. There are a range of similar species (many of them black) which doesn't help matters, but a larger size does narrow down the options to a degree. They are commonly found in horse and cattle dung and have a habit of withdrawing their appendages close to the body on disturbance.
