What was Liopleurodon?

This archive records Liopleurodon under the scientific name Liopleurodon ferox, with an age of About 166–155 million years ago and a range of European seas. A broad skull and four powerful flippers belonged to a leading Jurassic marine predator.

Liopleurodon was a large pliosaur that attacked fish and other marine reptiles. Its true length was impressive but far below some older popular estimates.

How was Liopleurodon built?

Overall body plan

A broad skull and four powerful flippers belonged to a leading Jurassic marine predator.

Skull and feeding apparatus

The available record is interpreted through preserved proportions, attachment surfaces, wear and comparison with related organisms. For Liopleurodon, those observations must be separated from features added only for visual reconstruction.

Axial skeleton and locomotion

Liopleurodon was a large pliosaur that attacked fish and other marine reptiles. Its true length was impressive but far below some older popular estimates.

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 Liopleurodon.

How did Liopleurodon live?

Liopleurodon was a large pliosaur that attacked fish and other marine reptiles. Its true length was impressive but far below some older popular estimates. This ecological reconstruction is strongest where anatomy, associated organisms and the depositional setting point in the same direction.

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.

Where and when did Liopleurodon live?

This archive currently lists About 166–155 million years ago; European seas. 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.

01

Documented geographic range

European seas. This boundary can change when specimens are reidentified or new localities are published.

02

Time window

About 166–155 million years ago, with the final recorded stage listed as Late Jurassic. Rock units and dating uncertainty mean the true biological range may extend beyond the known record.

03

Environmental setting

The archive uses the broad habitat labels Ocean. These labels help explore related records; a habitat reconstruction requires evidence from individual localities.

What evidence supports reconstructions of Liopleurodon?

01

Primary record

Skulls, teeth, limb bones and related skeletons establish its size and mechanics.

02

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.

03

Age and locality

Stratigraphy and occurrence records place Liopleurodon within About 166–155 million years ago and European seas. Reworked fossils and uncertain provenance are treated cautiously.

04

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.

Why did Liopleurodon disappear?

Late Jurassic ocean change and faunal turnover ended its lineage.

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.
