"Dinosaurs are the bridge between fantasy and reality. They are mythological creatures that left behind evidence of themselves unlike the Griffins and Unicorns of folklore."
Shannon Shea (Prehistoric Times, Issue #123, Fall 2017)
The Extinct Life Pictorial Encyclopedia is a virtual encyclopedia of extinct life ranging from microscopic critters to the legionary dinosaurs. This section of the website provides illustrations, images of fossils, photos of collectibles, and summary information about extinct life forms so that anyone of any age can see what these extinct creatures looked like as well as read high-level factoids.

Use caution; check the data before you use it. NOTE: the information presented throughout this website has NOT been reviewed by any person or organization. All information has been gathered and/or synthesized by me. I am doing my best to provide accurate data however, if you use material from this website for any reason, I would advise you do so with EXTREME CAUTION as there is a good chance that omissions, errors and/or outdated information may exist.

Sample life form listing.

Symbol Glossary
Data for this life form is complete The data for this life form is complete in terms of the information I am gathering which includes the life form’s name, applicable species, family group, author (e.g., paleontologist), extinction level (see below), geological time period(s), geographic fossil location(s), and images.
Life Form Family Group This image represents the family group to which the life form belongs such as the 'Tyrannosauroidea' as shown here. If you see this symbol Life Form Family Group Not Recorded, it means that I have not yet recorded a family group for this life form.
This life form is Globally Extinct.  or  At least one species of this life form still exists today. These symbols indicate the degree to which a life form is extinct. The This life form is Globally Extinct. symbol indicates a ‘genus-level extinction’ (a.k.a., global extinction) meaning that every species of that life form is lost forever. The At least one species of this life form still exists today. symbol indicates a ‘species-level extinction’ meaning that some species of this life form are extinct but others still exist today.
P Images of this life form are provided (e.g., artist illustrations, photos of fossils, photos of sculptures).
C Collectibles of this life form are provided (e.g., scans/photos of cards, stickers, etc.).

Life Forms
"No one knows the diversity in the world, not even to the nearest order of magnitude. … We don't know for sure how many species there are, where they can be found or how fast they're disappearing. It's like having astronomy without knowing where the stars are."
Edward O. Wilson
The number of identified extinct life forms (i.e., genus & species) is vast and constantly growing. The content of The Dinosaur Fan only scratches the surface with respect to the extinct life forms that have been documented. It is thought that approximately 99.9% of all species which have ever existed are extinct and that there are around 8.7 million species currently in existence. With this information, one can deduce that roughly 867 million extinct species once inhabited the planet Earth (ref. Science Daily, ‘How Many Species On Earth? About 8.7 Million, New Estimate Says’, August 24, 2011 (www.sciencedaily.com/releases/2011/08/110823180459.htm).

Below is a table showing an estimated distribution of life by kingdoms along with a comparative summary of the data currently contained in The Dinosaur Fan website. At the risk of stating the obvious, my site is missing several hundred-million species. So, if you have information pertaining to extinct life forms (e.g., genus, species, images, life form details) that you would like to share with The Dinosaur Fan readers, please contact me at: mmriley@dinofan.com and I’ll gladly add the information to the website and give you credit.

  * These are NOT officially recognized Kingdoms because the organisms are not considered to be “alive”. Viruses are inert particles that do not carry out metabolic functions on their own and cannot reproduce until they invade living host cells. 'Inanimatus' and 'Trace Fossils' are inanimate solids such as rocks, minerals, fossilized eggs, and trackways which according to human wisdom are not alive.

# These are legitimate Kingdoms however I have not found usable living and extinct population estimates. Fossil evidence of these creatures are rare.

     Food for thought …

"Finally, they came to granite. 'This is alive,' Leavitt said. 'It is living, breathing, walking, and talking. Only we cannot see it, because it is happening too slowly. Rock has a lifespan of three billion years. We have a lifespan of sixty or seventy years. We cannot see what is happening to this rock for the same reason that we cannot make out the tune of a record being played at a rate of one revolution every century. And the rock, for its part, is not even aware of our existence because we are alive for only a brief instant of its lifespan."
Michael Crichton, The Andromeda Strain

"It is absurd for the Evolutionist to complain that it is unthinkable for an admittedly unthinkable God to make everything out of nothing, and then pretend that it is more thinkable that nothing should turn itself into everything."
G.K. Chesterton
