Ectenosaurus
Ectenosaurus wuxuu ahaa xamaarato badeed si dhakhso ah u dabaasha oo ku noolayd badaha Late Cretaceous. Wuxuu lahaa san aad u dheer iyo jir adag, markaa wuxuu u dhaqaaqi jiray isagoo dabadiisa u ruxaya sidii kalluunka. Mosasaur-kan naadirka ah wuxuu ahaa ugaarsade sare oo ku noolayd badda qadiimiga ah.13

Xaqiiqooyin xiiso leh
Ectenosaurus wuxuu lahaa qolof yar, oo cabbirkeedu ahaa 2.7 by 2.0 mm, kuwaas oo ka yaraa kuwa mosasaurs-ka kale ee cabbirka la midka ah.1
Jirkiisu wuxuu ahaa mid adag xagga hore, markaa ma uu dhex-dhex mari karin sidii abeesada. Taa beddelkeeda, wuxuu isticmaali jiray baalka dabo si uu biyaha ugu riixo.1
Saynisyahannadu waxay heleen raadadka maqaarka Ectenosaurus oo muujinaya shabakad adag oo fiilooyin ah, taas oo ka caawisay inay fahmaan sida uu u dabaasho.1
Ectenosaurus waa mid ka mid ah mosasaurs-ka ugu dhifta badan, laakiin waxa uu lahaa ugu yaraan afar nooc oo kala duwan.2
Daraasadaha isotope-ka ee xasilloon waxay soo jeedinayaan in Ectenosaurus uu ku noolaa biyaha badweynta ee furan, ee ma ahayn oo kaliya meel u dhow xeebta.1
Fossilkii ugu horreeyay ee Ectenosaurus waxaa markii hore loo maleeyay inuu yahay nooc ka mid ah Platecarpus, laakiin saynisyahannada dambe ayaa siiyay magac u gaar ah.1

Burinta khuraafaadka
Khuraafaad: Dadka qaar waxay u maleynayaan in mosasaurs-ka sida Ectenosaurus ay u dabaalan jireen iyagoo jirka oo dhan u ruxaya sidii abeesada.
Runta: Dhab ahaantii, Ectenosaurus wuxuu lahaa jir hore oo adag wuxuuna u isticmaali jiray dabadiisa oo keliya dabaasha, si la mid ah nibiriyada casriga ah.1

- Wali waa la isku khilaafsan yahay
- Saynisyahannadu ma hubo in Ectenosaurus uu ka tirsan yahay subfamily-ga Plioplatecarpinae ama uu aad ugu dhow yahay mosasaurines-ka sida Prognathodon.1
