01 / ANSWER FIRST
What was Hyneria?
This archive records Hyneria under the scientific name Hyneria lindae, with an age of About 375–363 million years ago and a range of Euramerican estuaries and floodplains · Present-day Pennsylvania. This giant lobe-finned predator used fanglike teeth to ambush prey, while its fin skeleton followed a tetrapod-like pattern.
Hyneria was a large tetrapodomorph fish with a powerful tail for sudden acceleration in murky channels. Sensory canals detected water movement and several rows of teeth controlled large prey.

03 / ANATOMY
How was Hyneria built?
Overall body plan
This giant lobe-finned predator used fanglike teeth to ambush prey, while its fin skeleton followed a tetrapod-like pattern.
Skull, jaws and feeding surfaces
The available record is interpreted through preserved proportions, attachment surfaces, wear and comparison with related organisms. For Hyneria, those observations must be separated from features added only for visual reconstruction.
Fins and swimming body
Hyneria was a large tetrapodomorph fish with a powerful tail for sudden acceleration in murky channels. Sensory canals detected water movement and several rows of teeth controlled large prey.
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 Hyneria.
04 / DIET & BEHAVIOUR
How did Hyneria live?
Hyneria was a large tetrapodomorph fish with a powerful tail for sudden acceleration in murky channels. Sensory canals detected water movement and several rows of teeth controlled large prey. 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 water depth, current, oxygen, prey and nursery habitat. 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 Hyneria live?
This archive currently lists About 375–363 million years ago; Euramerican estuaries and floodplains · Present-day Pennsylvania. 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
Euramerican estuaries and floodplains · Present-day Pennsylvania. This boundary can change when specimens are reidentified or new localities are published.
Time window
About 375–363 million years ago, with the final recorded stage listed as Late Devonian. 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 Wetland. These labels help explore related records; a habitat reconstruction requires evidence from individual localities.
07 / FOSSIL EVIDENCE
What evidence supports reconstructions of Hyneria?
Primary record
Red Hill skulls, shoulder girdles, fin bones and scales reveal size, predatory anatomy and a tetrapod-like limb-bone sequence.
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 Hyneria within About 375–363 million years ago and Euramerican estuaries and floodplains · Present-day Pennsylvania. 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.
08 / DISAPPEARANCE & DEBATE
Why did Hyneria disappear?
Repeated Late Devonian oxygen crises and drainage changes disrupted freshwater and estuarine food webs, eliminating many giant lobe-finned lineages.
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.
