A palaeogravity calculation for the ancient land scorpion Pulmonoscorpius kirktonensis

 One fundamental technique to quantify palaeogravity is to compare dynamically similar extinct and extant
 animals. This technique is applied to the ancient land scorpion Pulmonoscorpius kirktonensis. The results
 indicate a palaeogravity of about 0.33g existed 330 million years ago.
