Dinosaurs turnovers during the Jurassic–Cretaceous transition driven by climate shifts and biotic interactions

This folder contains all the original datasets, scripts, and results used in the study: raw_data:- raw_data_PBDB.csv: Raw occurrence data exported from the Paleobiology Database (PBDB), including all vertebrate fossil records from the Aalenian to Albian stages (174.7–100.5 Ma).- dino.xlsx: Species-level dinosaur database after data cleaning and augmentation; red-highlighted fields indicate variables essential or relevant to the analyses.- dino_singleton.xlsx: Species-level dinosaur database with all singleton taxa excluded; red-highlighted fields indicate variables essential or relevant to the analyses.- dino1.xlsx: Genus-level dinosaur database after data cleaning and augmentation; red-highlighted fields indicate variables essential or relevant to the analyses.- dino1_singleton.xlsx: Genus-level dinosaur database with all singleton taxa excluded; red-highlighted fields indicate variables essential or relevant to the analyses. b_data - epochs_q.txt: Defines rate shift intervals in the PyRate analysis using a Time-Variable Poisson Process model, aligned with geological stages. - time_windows_a5.txt: Specifies time bins (0.5 Myr resolution) used in the PyRateBDNN analysis. - dino_con_e_165_125.txt: Time-continuous variables applied in PyRateBDNN modeling. - Backscale_e_165_125(_l).txt: Z-transformed means and standard deviations of time-continuous variables used for back-scaling model outputs to original data scales. gen_dino1 (Genus-level dinosaur diversification analysis) - gen_dino1.py: Input dataset for PyRate analysis. - gen_dino1_trait.txt: Trait data for each taxon in the PyRateBDNN model. - RTT_groups_dino_gn_cl.csv: Species grouped by clade for RTT analysis in PyRateBDNN. - RTT_groups_dino_gn_le.csv: Species grouped by body size for RTT analysis in PyRateBDNN. - bash: Scripts for running PyRate and PyRateBDNN analyses. - result: Output from PyRate runs. - bdnn1_tw: Results from PyRateBDNN runs. gen_dino1_singleton (Genus-level analysis excluding singleton taxa) - Files follow the same structure and naming conventions as in gen_dino1, adapted for analyses excluding singletons. sp_dino (Species-level dinosaur diversification analysis) - sp_dino.py: Input dataset for PyRate analysis. - sp_dino_trait_tw.txt: Trait data for PyRateBDNN modeling. - RTT_groups_dino_sp_cl.csv: Species grouped by clade. - RTT_groups_dino_sp_le.csv: Species grouped by body size. - RTT_groups_dino_sp_ar.csv: Species grouped by palaeogeographic region. - bash: Scripts for running PyRate and PyRateBDNN analyses. - result: Output from PyRate runs. - bdnn1_tw: Results from PyRateBDNN runs. sp_dino_singleton (Species-level analysis excluding singleton taxa) - Files follow the same structure as sp_dino, adapted for analyses excluding singleton occurrences. J_K_result: Contains all results from the PyRate and PyRateBDNN analyses. The contents of each folder correspond to those described above. Files prefixed with RTT_group represent the RTT results from PyRateBDNN for each taxonomic group, body size category, or palaeogeographic region.
