01 / ANSWER FIRST
What was Pteranodon?
This archive records Pteranodon under the scientific name Pteranodon longiceps, with an age of About 86–84 million years ago and a range of Western Interior Seaway of North America. Long wings and a toothless beak carried this pterosaur over an inland sea.
Pteranodon launched from shore and soared above open water to take fish. Adults differed strongly in body size and crest shape.

03 / ANATOMY
How was Pteranodon built?
Overall body plan
Long wings and a toothless beak carried this pterosaur over an inland sea.
Skull and feeding apparatus
The available record is interpreted through preserved proportions, attachment surfaces, wear and comparison with related organisms. For Pteranodon, those observations must be separated from features added only for visual reconstruction.
Axial skeleton and locomotion
Pteranodon launched from shore and soared above open water to take fish. Adults differed strongly in body size and crest shape.
Growth and individual variation
A single specimen does not define the whole species. Size, maturity, preservation and possible sex differences are considered before anatomical traits are treated as typical of Pteranodon.
04 / DIET & BEHAVIOUR
How did Pteranodon live?
Pteranodon launched from shore and soared above open water to take fish. Adults differed strongly in body size and crest shape. This ecological reconstruction is strongest where anatomy, associated organisms and the depositional setting point in the same direction.
05 / DIET & BEHAVIOUR
What shaped its ecological limits?
Its populations depended on temperature, nesting habitat, prey or vegetation, and connected landscapes. Changes in any one factor did not necessarily cause immediate extinction, but interacting pressures could reduce range, recruitment and resilience.
06 / RANGE & HABITAT
Where and when did Pteranodon live?
This archive currently lists About 86–84 million years ago; Western Interior Seaway of North America. Fossil or historical occurrence data describe where evidence has been found, not every place the taxon once occupied. Species-level age and range limits still require source-specific review.
Documented geographic range
Western Interior Seaway of North America. This boundary can change when specimens are reidentified or new localities are published.
Time window
About 86–84 million years ago, with the final recorded stage listed as Late Cretaceous. Rock units and dating uncertainty mean the true biological range may extend beyond the known record.
Environmental setting
The archive uses the broad habitat labels Ocean. These labels help explore related records; a habitat reconstruction requires evidence from individual localities.
07 / FOSSIL EVIDENCE
What evidence supports reconstructions of Pteranodon?
Primary record
Hundreds of skeletons, fish remains and flight models reveal its marine life.
Comparative anatomy
Preserved structures are compared with close and functionally similar organisms. The method can constrain posture and function, but analogy alone cannot prove colour, behaviour or soft tissue.
Age and locality
Stratigraphy and occurrence records place Pteranodon within About 86–84 million years ago and Western Interior Seaway of North America. Reworked fossils and uncertain provenance are treated cautiously.
Open entity records
Links below connect the archive to available taxonomic and occurrence records. A matching name does not verify every ecological claim, and related-taxon links provide comparison rather than an exact species match.
Evidence limits for this record
The museum dates Pteranodon longiceps to about 85 million years ago; this is not evidence of survival to the end-Cretaceous impact.
08 / DISAPPEARANCE & DEBATE
Why did Pteranodon disappear?
The age recorded here predates the end-Cretaceous impact. Marine environmental change provides context, but this archive does not establish a direct cause for the disappearance of this species.
The last fossil or observation marks the youngest evidence currently known, not necessarily the death of the final individual. Explanations are strongest when timing, environmental change and population biology agree; otherwise the profile preserves uncertainty instead of assigning a single dramatic cause.
