Fossil price guides
Educational price context for a live marketplace — how to compare lots, read sample category ranges, and move from a number to sold results, market trends, and the hold map on each listing.
Disclaimer: Jurassic Depot price guides are educational marketplace context only. They are not an appraisal, authenticity guarantee, legal opinion, or investment advice. Fossils are illiquid collectibles — past asks, sample ranges, and hold-map outlooks do not predict future sale prices.
Resource Hub Guide
Educational comparison habits for a live fossil marketplace — not appraisals.
How to use price context
Treat every figure as a starting question. Work through these steps before you bid, list, or negotiate.
- 1Open sold results →
Separate asks from solds
An active bid or Buy Now is not a completed sale. Start with sold results, then compare to live lots.
- 2Documentation checklist →
Match condition fields first
Only treat two pieces as comparable after provenance, restoration, size, and documentation line up.
- 3Market trends →
Read category context
Use educational sample ranges and market-trend drivers as orientation — not as a quote for your piece.
- 4Browse live auctions →
Check the hold map on the lot
Each showcase lot has a Jurassic Depot hold map for educational outlook framing. Sellers cannot edit those numbers.
Comparison checklist
A similar photo is not a similar fossil. Run these four fields before trusting any “comp.”
Provenance
Country, land status, chain of custody, and whether locality is public or private on file.
Restoration
Repair %, composites, coatings, replaced sections, and how clearly the seller discloses them.
Size & completeness
Measured length/mass, missing tips or roots, and whether scale photos support the claim.
Documentation
Landowner releases, export/import paths, receipts, and what is still missing or redacted.

How to use guides →
SampleSize & condition
Length, mass, and completeness shift ranges more than title keywords alone.
Open checklist →
SampleRestoration review
Repair and rebuild percentage should sit next to every comparison number.
Category lanes →
SampleDocs on the desk
Provenance and export files change what a “similar” sold result can mean.
Documentation rules →
SampleSold-result review
Use sold records and active lots together — asks are not completed sales.

Sample. Showcase photos are labeled Sample. They illustrate layout and atmosphere — not a claim that every image is a live seller’s inventory photo.
Category lanes
SampleEducational sample ranges from showcase lots on Jurassic Depot. Labeled Sample — not audited market medians or inventory quotes.
Dinosaur teeth
SampleHell Creek and similar theropod material — size, enamel, and land docs move the range.
Sample context range
$4,800
Shark teeth
SampleMegalodon and large Miocene teeth — serration, root completeness, and locality notes matter.
Sample context range
$1,850
Marine reptiles
SampleMosasaur and related jaw / tooth lots — restoration % and export path often dominate comps.
Sample context range
$3,900
Invertebrates
SampleTrilobites and ammonites — prep quality and paperwork gaps can outweigh visual appeal.
Sample context range
$295 – $525
Ice-age mammals
SampleMammoth and Pleistocene material — legality and transport docs sit next to any figure.
Sample context range
$4,200
Ranges use current bid or Buy Now on showcase lots only. They illustrate comparison habits — not what your specimen will sell for.
Hold map concept
Outlook framing on every lot
The Jurassic Depot hold map is an educational outlook built from listing scores and category heuristics — thin vs. sought lanes, sample 5- and 10-year bands, and flip-risk notes. Sellers cannot edit the numbers. It is not a guarantee of future value.

Limits worth repeating
- — Sample ranges are showcase educational context, not a published price index.
- — Asking prices and hold-map bands are not guarantees of what a piece will sell for.
- — Missing docs, heavy restoration, or restricted origin can void a visual “comp.”
- — Nothing on this page is appraisal, authentication, legal, or investment advice.
