Hylonomus is an extinct reptile from the late carboniferous period,312 mya.it is the earliest unquestionable reptile(westlothiana is older,but in fact it may haved been an amphibian and casineria is rather fragmentary).the only species is the type species hylonomus lyelli
Hylonomus was 20-25 cm(8-10 in)long(including the tail).most of them are 20 cm long and would probably haved looked similar to modern lizards.it had small sharp teeth and it likely ate small invertebrates such as millipedes or early insects
This creature was discovered by lohn william dawson in mid-19th century.the species's name name was given it by dawson's teacher,the geologist sir charles lyell.while it has traditionally bern included in the group protorothyrididae,later studies shown that it is probably more closely related to diapsids
Hylonomus lyelli was named the provincial fossil of nova dcotia in 2002
