Supplementary information contains:
 Dataset.Body.Size.Opazo&Twitchett2021.csv_Paleobiology contains one spreadsheet with all body size measurements used in this study. This file is made up of 17 columns which indicates: 
 Formation = Corresponds to stratigraphic units (and biozones) considered in this study: 
WF: Westbury Formation/ CM: Cotham Member/ LM: Langport Member/ PPZ=Pre-Planorbis Zone/ PZ=Planorbis Zone/ LZ: Liasicus Zone/ AZ: Angulata Zone 
Locality = NI: Larne, Northern Ireland/PB: Pinhay Bay, Devon/AB: St. Audrie's Bay (all from United Kingdom) Sample = Sample Code Heights (m) = Stratigraphic height Tier = Infaunal/Surficial/Semi-infaunal Taxonomy=Order/Family/Genus/Species
 Ecological categories: Colonizers/Extinct/Survivors
Length (mm) = Maximum distance on the anterior–posterior axis Height (mm) = Maximum distance on the dorsal-ventral axis BS (mm) = Body size expressed as geometric mean (i.e., the square root of the product of length and width) log2 (BS) = log2 of the geometric mean Residuals = Grand bivalves mean (log2) minus the body size (log2) of each specimen Lithology = Mudstone/Limestone Opazo&Twitchett2021.Supplementary.text.pdf_Paleobiology: This file contains information regarding paleoenvironment, extinction event and the Triassic/Jurassic Boundary, and geological setting of the Triassic/Jurassic Boundary in the United Kingdom.
