Measurement download request form

What to include Other options Output fields
This form allows you to download average measurements of fossil specimens grouped by species. To download occurrences of taxa within fossil collections, use the form for collection and occurrence data. To download taxonomic classification data, use the form for names and opinions.
Taxonomic group (required):
Excluding this taxon:
Group records by senior synonym?
Taxonomic resolution:
Only occurrences have qualified IDs, so measurements
tied to species names instead of occurrences will
always be included.
Extant or extinct taxa?
Included life habit categories: fossorial semifossorial ground dwelling saltatorial scansorial
arboreal volant amphibious fully aquatic
Specimens and measurements
Sex of specimens:
Body parts:
Optional. Lists such as m1, skull, shell are okay.
all parts must be measured
Length measurements: not recorded greatest least anteroposterior basal
condylobasal condyloincisive
Width measurements: not recorded greatest least anterior distal mediolateral posterior
proximal transverse orbital quadrate zygomatic
Included collections
If you pick any of these options you will only get back measurements of specimens tied to individual fossil collections.

Fossil collection fields
These fields are (1) only reported for measurements of specimens that are tied to particular fossil occurrences and (2) only printed to the raw measurements file (because they cannot be averaged sensibly).
