- Paratomistoma (meaning "next to or near Tomistoma") is an extinct monospecific genus of gavialoid crocodylian. It is based on the holotype specimen CGM 42188, a partial posterior skull and lower jaw discovered at Wadi Hitan, Egypt, in Middle Eocene-age rocks of the . The skull is unfused but considered morphologically mature. Paratomistoma was named in 2000 by Christopher Brochu and Philip Gingerich; the type species is P. courti in honor of Nicholas Court, who found CGM 42188. They performed a phylogenetic analysis and found Paratomistoma to be a derived member of Tomistominae, related to the false gharial. It may have been a marine or coastal crocodilian. Below is a cladogram based morphological studies comparing skeletal features that shows Paratomistoma as a member of Tomistominae: Based on morphological studies of extinct taxa, the tomistomines were long thought to be classified as crocodiles and not closely related to gavialoids. However, recent molecular studies using DNA sequencing have consistently indicated that the false gharial (Tomistoma) (and by inference other related extinct forms in Tomistominae) actually belong to Gavialoidea (and Gavialidae). Below is a cladogram from a 2018 tip dating study by Lee & Yates simultaneously using morphological, molecular (DNA sequencing), and stratigraphic (fossil age) data that shows Paratomistoma as an early-diverging gavialoid, more basal than the last common ancestor to both the gharial and the false gharial: (en)
- 副切喙鳄属（学名：Paratomistoma，意为“next to or near Tomistoma”）是一属灭绝的切喙鳄亚科鳄鱼。对它的认识主要基于模式标本CGM 42188，包含部分后颅骨和下颌，其被发现于埃及瓦迪希坦Gehannam组的中始新世时期岩石中。它的头骨是未融合的，但被认为是形态上成熟的。副切喙鳄属于2000年由Christopher Brochu和命名，模式种是P. courti，这是为了纪念Nicholas Court，他发现了CGM 42188。他们进行了系统发育分析，发现副切喙鳄属是一属派生的切喙鳄亚科。 它可能是海栖或沿海生活的鳄鱼。 (zh)
