Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. Churchill et al. 2016 | Echovenator has the following synapomorphies of Xenorophi- dae: premaxilla underlies the ascending process of the maxilla, a frontal window that exposes the maxilla and premaxilla, and an elongate ventrolateral tuberosity of the periotic [6, 7]. Echove- nator differs from all xenorophids in having fused, or partially fused, fronto-nasal and maxillo-premaxillary sutures and in having a paranaris fossa; it differs from Xenorophus sloanii and Albertocetus meffordorum in having a postnarial fossa and a depressed internasal suture; and it differs from Cotylocara macei in having an undivided postnarial fossa and in having larger dorsal exposures of parietals. |
