The Diplodocus Reference Guide

A plain, sourced guide to Diplodocus — the animal, the Carnegie mount, Dippy in London, and the published length figures — with a comparison table that keeps museum and paper numbers labelled where they differ, and credited public-domain and CC BY photographs.

What’s inside:

- How to use this guide

- The animal

- Name, neck and chevrons

- How long was it? A sourced comparison table

- Compared with a bus, and the weight problem

- Dippy in London, including a later photograph

- Discovery, and the house that Dippy built

- What is actually mounted

- When it lived, credits and sources

Pages: 11 (A4) / 11 (US Letter). Formats: A4 (210 × 297 mm) and US Letter (8.5 × 11 in), both PDFs included in one zip.

Printing: Print at 100% / actual size on A4 or US Letter. Most inside pages use light backgrounds and print well in black and white; the cover is dark, so print that in colour or skip it to save ink.

Every fact is written in our own words and checked against named sources (the Natural History Museum Dino Directory and Dippy pages, “Dippy: this is your life”, Carnegie Museum essays, Taylor, Wedel and Moacdieh 2025, and Encyclopaedia Britannica), checked 15 November 2026. The sources are listed on the credits page. Where museums and papers print different lengths, weights or date ranges, both are shown and labelled.

Images are public-domain or CC BY photographs and one 1901 scientific plate, credited on the credits page, and resized with no other changes. Captions say when a picture is a mounted composite, a plaster cast, or an illustration. This pack is independent and is not affiliated with, or endorsed by, the Natural History Museum, the Carnegie Museum of Natural History, or Encyclopaedia Britannica.
