Leptocleididae
Leptocleididae is a family of small-sized plesiosaurs that lived during the Early Cretaceous period (early Berriasian to early Albian stage).[1] Leptocleidus and Umoonasaurus had round bodies and triangle-shaped heads. Hilary F. Ketchum and Roger B. J. Benson (2010), transferred Brancasaurus, Kaiwhekea, Nichollssaura and Thililua to this family.[2] However, Ketchum and Benson (2011) reassigned Kaiwhekea and Thililua to their original positions, as an elasmosaurid and a polycotylid, respectively.[1]

gollark: Great, right?
gollark: So really, stuff can break for no apparent reason with no recourse other than randomly restarting things.
gollark: See, networking is awful and everything barely holds together on several levels.
gollark: WiFi is somewhat insecure because apparently the... Wi-Fi Alliance, I think? repeatedly manage to be idiots who make stupid design mistakes which don't get fixed even when people point them out prior to WPA-n, n∈ℕ standardization.
gollark: Public key.
