DINOSAURIA FROM THE 
Case. Comp. Tablet. Specimen. 
together. The neural arch is small and 
very much depressed. 
J 2 d 7 1—4 caudal vertebrae anchylosed, with chevron bones 
and neural arches preserved. 
2 c? 8 1—4 sacral vertebrae probably Dinosaurian ; both 
neural arches and transverse processes are 
wanting. 
de 9 1—8 caudal vertebrae, centrum depressed and slightly 
oblique, flattened or cupped in front, ball 
behind; neural arch on its anterior half; 
zygapophyses long, no chevron bones. 
2 d 10 1—5 dermal armour of a dinosaur. 1, 2, and 3 show 
the under sides of plates; 4 and 5 the 
outsides. 1 and 2 show the scars of the 
muscles to which the plates were attached. 
The plates all have an elevated crest, 
sometimes as in 5 produced into a spine. 
e 1 1—2 a very large rib imperfect at both ends; 
characters chiefly crocodilian. A small rib 
with two tubercles at the proximal end. 
e 2 1 tibia * 5J inches long. Slender in the shaft, 
curved and compressed. Testudinarian in 
character, distal end well preserved, 
e 3 1 tibia * of an animal nearly allied to the last: 
the bone is 8^ inches long, and worn at 
the proximal end. 
e 4 1 ulna* straighter in its outlines and more mas¬ 
sive than the ? tibia, 6 inches long, proxi¬ 
mal end worn. Distal end relatively large. 
e 5 1 ulna* similar to last, showing form of proximal 
end. It is 8^ inches long. 
e 6 1 middle metatarsal bone 7^ inches long. 
e 7 1—4 three phalanges and a claw-phalange associated. 
e 8 1—5 three metacarpal bones, a phalange and an 
elongated claw-phalange associated. 
* On the hypothesis of Chelonian affinities predominating in the animal. 
If the affinities were chiefly Crocodilian, then the supposed tibia would be 
an ulna.
