A monotaxic bonebed containing numerous phytosaur specimens is reported from the Upper Triassic Tiki Formation of India. The comprehensive minimum number of individuals is estimated to be 21, which includes multiple juveniles and subadults, and only a few adults. Such intraspecific aggregation of juvenile-dominated phytosaurs is explained here by parental care and juveniles living in cohorts, as are evident from extant phylogenetic bracketing of either lepidosaurs or crocodiles and birds. The cause of this mass death is probably disease related, after which the carcasses bloated, floated, and disarticulated at the site of death, resulting in an autochthonous assemblage. The carcasses remained submerged under shallow, slow-moving or standing water for a prolonged time and later were subaerially exposed after the recession of water. Subsequently, flooding events resulted in their burial under the overbank fines. Comparison of biostratinomic variables with those of a rhynchosaur-dominated bonebed recovered previously from the same stratigraphic horizon showed distinct differences in their causes of death and fossilization pathways. The latter may be attributed to their habitat differences because the phytosaurs lived in the low-lying areas or ponds and the rhynchosaurs resided on relatively higher and drier areas of the Tiki floodplain.

印度上三叠世提基组据报道含有许多植物龙标本的单层骨床。估计的整体最低人数为21，其中包括多个少年和亚成人，只有几个成年人。幼体占主导地位的植物龙骨的这种种内聚集在这里由父母的照料和生活在队列中的幼体来解释，这从鳞翅目或鳄鱼和鸟类的现成系统支架中可以看出。这种大规模死亡的原因可能与疾病有关，此后，尸体在死亡部位肿，浮起并脱开关节，导致了土生土长的组合。尸体长时间浸没在浅水，缓慢移动或静水下，随后在水衰退后暴露在地下。后来，洪水事件导致他们被埋葬，处以罚款。将生物地层学变量与先前从同一地层视野中恢复的以菱形龙为主的骨床的生物地层学变量进行比较，发现它们的死亡原因和化石途径存在明显差异。后者可能是由于它们的生境差异所致，因为植物龙生活在低洼地区或池塘中，而长龙则生活在提基洪泛区的相对较高和较干燥的地区。
