This brachiopod assemblage includes mostly genera not recorded previously from contemporaneous deposits in Kazakhstan, although they may be related to the long-lived lineages which appeared in the area during Llanvirn or Llandeilo.

Cretaceous bryozoans are rare in Australasia, and the two species in this paper are the first to be formally described from New Zealand. Both species have thick dendroid colonies but whereas Ceriocava maculata sp. nov. is an unequivocal cerioporine cyclostome, the other species — Chiplonkarina campbelli sp. nov. — is more problematical and is interpreted as an aberrant ‘malacostegan’ cheilostome. Like previously described species of Chiplonkarina, C. campbelli has interzooidal walls with a central crenulated layer, indicating the former presence of an intercalary cuticle of the type found in many cheilostomes but unknown in cyclostomes. The anomalous global biogeographical distribution of bryozoans during the Cretaceous is briefly discussed.","PeriodicalId":50830,"journal":{"name":"Alcheringa","volume":"20 1","pages":"315-327"},"PeriodicalIF":1.3,"publicationDate":"1996-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03115519608619474","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59987124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Paired processes for the flexor tendons on the proximoventral margin of phalanx 1 digit III are absent. Relative proportions of the phalanges and number of phalanges in digits II and III are similar to those of dromornithids.

Jawonya gurumal from the Tindall Limestone near Claravale is better preserved than type and topotype material, and demonstrates that the genus is two-walled, and not one-walled as originally described. Furthermore, exopore architecture is much more complex than previously envisaged. The co-occurring related genus Wagima is also considered to be two-walled.

The new species differs from Kambara murgonensis in several features, the most significant of which is possession of an interlocking dentition. Both species occur in a single stratigraphic horizon, possibly indicating two sympatric populations. The presence of adults and hatclings, coupled with the rarity of intermediately sized animals in the Murgon sample suggests the area may have been used as a nesting ground by one or both species.
