A new study finds that the Mesozoic Era saw significantly higher quantities of the greenhouse gas than both pre-industrial and modern levels, likely due to volcanic activity

The S. rapax fossil was initially smuggled out of Mongolia but has since been returned to the country. Its skull and a few vertebrae were lost, but not before scientists took CT scans of the skeleton.
