01 / ANSWER FIRST
What was Bothriolepis?
This archive records Bothriolepis under the scientific name Bothriolepis canadensis, with an age of About 387–360 million years ago and a range of Euramerican rivers and lakes · Present-day Canada. Bony armor enclosed its head and chest while jointed pectoral appendages steadied it on the bottom.
Bothriolepis was a flattened placoderm that lived low in freshwater habitats. It probably drew small food and organic matter from sediment and tolerated variable water levels and oxygen.

03 / ANATOMY
How was Bothriolepis built?
Overall body plan
Bony armor enclosed its head and chest while jointed pectoral appendages steadied it on the bottom.
Skull, jaws and feeding surfaces
The available record is interpreted through preserved proportions, attachment surfaces, wear and comparison with related organisms. For Bothriolepis, those observations must be separated from features added only for visual reconstruction.
Fins and swimming body
Bothriolepis was a flattened placoderm that lived low in freshwater habitats. It probably drew small food and organic matter from sediment and tolerated variable water levels and oxygen.
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 Bothriolepis.
04 / DIET & BEHAVIOUR
How did Bothriolepis live?
Bothriolepis was a flattened placoderm that lived low in freshwater habitats. It probably drew small food and organic matter from sediment and tolerated variable water levels and oxygen. 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 Bothriolepis live?
This archive currently lists About 387–360 million years ago; Euramerican rivers and lakes · Present-day Canada. 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 rivers and lakes · Present-day Canada. This boundary can change when specimens are reidentified or new localities are published.
Time window
About 387–360 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 Freshwater. These labels help explore related records; a habitat reconstruction requires evidence from individual localities.
07 / FOSSIL EVIDENCE
What evidence supports reconstructions of Bothriolepis?
Primary record
Articulated armor, body outlines and mass assemblages preserve its proportions and habitat.
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 Bothriolepis within About 387–360 million years ago and Euramerican rivers and lakes · Present-day Canada. 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 Bothriolepis disappear?
Late Devonian anoxia, climate shifts and freshwater turnover ended the antiarch 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.
