The Royal Tyrrell Mu­seum of Palaeon­tol­ogy’s 2018 Speaker Se­ries starts this Thurs­day, Jan­uary 18. with, First Steps onto the Tan­gled Bank: Evo­lu­tion­ary Ex­per­i­ments in the Early Te­tra­pod Form. Ja­son Pardo, Ph. D. can­di­date at the Uni­ver­sity of Cal­gary will open the 2018 Speaker Se­ries with his pre­sen­ta­tion” First Steps onto the Tan­gled Bank: Evo­lu­tion­ary Ex­per­i­ments in the Early Te­tra­pod Form.”

This talk will be pre­sented by Ja­son Pardo, Ph. D. can­di­date at the Uni­ver­sity of Cal­gary.

The early ori­gins of am­phib­ians (frogs, sala­man- ders, and cae­cil­ians) are not well un­der­stood. This is due to their rar­ity in the early fos­sil record, as well as in­com­plete sci­en­tific un­der­stand­ing of four-legged ver­te­brate (te­tra­pod) evo­lu­tion and the anatomy of pos­si­ble am­phib­ian rel­a­tives. Newly dis­cov­ered fos­sils from the Tri­as­sic Pe­riod give us in­sights into the ori­gins of cae­cil­ians, a group of limb­less am­phib­ians from trop­i­cal rain­forests around the globe.

This re­search con­trib­utes to an emerg­ing pic­ture of the early evo­lu­tion of tetrapods, of which the ori­gin of mod­ern am­phib­ians is a part.

In his pre­sen­ta­tion, Ja­son Pardo will talk about ad­dress­ing the gaps in sci­en­tific un­der­stand­ing of early te­tra­pod evo­lu­tion. Pardo and his col­leagues used high-res­o­lu­tion med­i­cal imag­ing tech­nolo­gies to learn more about the pos­si­ble fos­sil an­ces­tors of mod­ern am­phib­ians.

The Royal Tyrrell Mu­seum’s Speaker Se­ries talks are free and open to the pub­lic.

The se­ries will be held ev­ery Thurs­day un­til April 26 at 11:00 a.m. in the Mu­seum au­di­to­rium.

Speaker Se­ries talks are also avail­able on the Mu­seum’s YouTube chan­nel: youtube. com/ c/ Roy­alTyrrel­lMu­se­u­mofPalaeon­tol­ogy.
